Description
- This application is a divisional of U.S. Pat. Application No. 17/207,648, filed Mar. 20, 2021, which is a continuation of International Patent Application No. PCT/CN2019/111824, filed Oct. 18, 2019, which claims the benefit of European Patent Application No. 18202098.2, filed Oct. 23, 2018, the disclosures of which are incorporated herein by reference in their entireties.
- The disclosure relates to a fastening arrangement for fastening a vehicle sliding door to a vehicle body while enabling opening and closing of the sliding door. The disclosure also relates to a vehicle having such a fastening arrangement, and a method for opening a sliding door of a vehicle having a vehicle body and a fastening arrangement for fastening the sliding door to the vehicle body while enabling opening and closing of the sliding door.
- Although the disclosure will be described in relation to a car, the disclosure is not restricted to this particular type of vehicle, but may alternatively be installed in other types of vehicles such as minivans, recreational vehicles, off-road vehicles, trucks, buses, marine vehicles, air vehicles, or the like.
- Doors for enabling access to vehicle can be opened and closed in a variety of ways, such as for example by means of a pivotal or sliding opening and closing motion. Sliding doors does not extend much laterally beyond the lateral side surface of the vehicle in opened position making sliding doors an attractive design solution. Sliding door also enables a relatively large opening for simplified entering or leaving the vehicle.
- This section provides a general summary of the disclosure, and is not a comprehensive disclosure of its full scope or all of its features.
- A sliding door moving from a closed position to an open position typically undergo two motion sequences: A first motion sequence in which the sliding door is displaced simultaneously both laterally outwardly and longitudinally along a length direction of the vehicle body, from a closed position to an intermediate position, and subsequently a second motion sequence in which the sliding door is displaced substantially longitudinally along a length direction of the vehicle body, from the intermediate position to an open position of the sliding door. The closing of the sliding door involves the same motion sequences but performed in reversed order and direction.
- Sliding doors are generally attached to guiding rails of the vehicle body via a plurality of solid and non-adjustable brackets, wherein at least the lower guiding rail located at the rocker of the vehicle body is generally bent inwardly towards a centre line of the vehicle in the area where the bracket is located in a closed position of the sliding door for enabling the sliding door to move laterally inwardly in the region of the closed position of the sliding door.
- Consequently, a problem with currently available fastening arrangements for sliding doors is that they generally require a large space within the vehicle body in the area of said fastening arrangements due to the inwardly curved design of the guiding rail. This is particularly problematic for electrical of hybrid electric vehicle where the floor region of the vehicle often is used for storing the propulsion battery making inwardly curved guiding rails undesirable, and/or vehicles having straight rockers made of extruded aluminium beams, such that mounting of inwardly curved guiding rails would require additional costly manufacturing processing of the straight extruded beams, as well as weakening the strength of said straight beams, because an inwardly curved guiding rail would require material removing machining of the straight extruded aluminium profile for creating space for the inwardly curved guide rail.
- An object of the present disclosure is consequently to provide a fastening system for a sliding door of a vehicle that enables opening or closing of the sliding door while avoiding inwardly curved guiding rails, at least for the guiding rail located at the rocker of the vehicle.
- The objective is at least partly achieved by a fastening arrangement and method as defined in the accompanying independent claims.
- In particular, according to a first aspect of the present disclosure, the objective is at least partly achieved by a fastening arrangement for fastening a vehicle sliding door to a vehicle body while enabling opening and closing of the sliding door, wherein the fastening arrangement comprises a motion element configured for being movingly arranged within or on a vehicle body guiding rail for enabling movement of the motion element along the vehicle body guiding rail, wherein the fastening arrangement further comprises a variable-length motion mechanism connected to the motion element and configured for being fastened to the sliding door at a lower attachment area of the sliding door, and wherein the variable-length motion mechanism is configured for enabling variable distance between the motion element and the lower attachment area of the sliding door.
- Moreover, according to a second aspect of the present disclosure, the objective is also at least partly achieved by method for opening a sliding door of a vehicle having a vehicle body and a fastening arrangement for fastening the sliding door to the vehicle body while enabling opening and closing of the sliding door, wherein the fastening arrangement comprises a motion element movingly arranged within or on a vehicle body guiding rail for enabling movement of the motion element along the vehicle body guiding rail, and a variable-length motion mechanism connected to the motion element and fastened to the sliding door at a lower attachment area of the sliding door, wherein the method comprises performing a first motion sequence involving extension of the variable-length motion mechanism from a contracted state to an extended state, thereby causing the sliding door to displace from a closed position to an intermediate position while the motion element remains substantially stationary, and subsequently performing a second motion sequence involving displacing the motion element along the vehicle body guiding rail, thereby causing the sliding door to displace primarily in a longitudinal direction of the vehicle body from the intermediate position to an open position of the sliding door while the variable-length motion mechanism remains in the extended state.
- In this way, it becomes possible to have a substantially straight and linear vehicle body guiding rail, because the required lateral inwards motion of the sliding door configured to take place upon approaching the closed position of the sliding door is provided by the variable-length motion mechanism being adjusted from the extended state to the contracted state.
- In other words, the opening and closing motion of the sliding door as such remains substantially the same while the guiding rail may have a substantially linear shape instead of an inwardly curved shape, thereby avoiding intruding into the space intended for propulsion battery storage, and avoiding additional manufacturing processing of an extruded straight aluminium rocker if such is used as rocker beam of the vehicle body.
- Further advantages are achieved by implementing one or several of the features of the dependent claims.
- In some example embodiments, the variable-length motion mechanism is configured for providing a first distance between the motion element and the lower attachment area of the sliding door in a closed position of the sliding door and a second distance between the motion element and the lower attachment area of the sliding door in an open position of the sliding door, wherein the second distance is larger than the first distance. Thereby the necessary lateral motion of the sliding door is accomplished without need for a curved guide rail, such that straight guide rail can be used.
- In some example embodiments, the variable-length motion mechanism includes an arm and a travel element, wherein the arm is pivotally connected to the motion element, wherein the travel element is secured to, and can travel along the length of, the arm, and wherein the travel element is configured for being fastened to the sliding door at the lower attachment area of the sliding door for enabling variable distance between the motion element and the lower attachment area of the sliding door. Thereby, a relatively low-cost but still robust and effective variable distance mounting of the lower side of the door to the vehicle is provided.
- In some example embodiments, the variable-length motion mechanism includes a mechanical spring having a first end and a second end, wherein the first end is connected to the motion element or an end region of the arm being connected to the motion element, and the second end is connected to the travel element. Thereby, closing of the sliding door is simplified, since the mechanical spring becomes tensioned upon opening the door and subsequently more relaxed again upon closing the door.
- In some example embodiments, the variable-length motion mechanism is a variable-length motion actuator configured for enabling powered variable distance between the motion element and the lower attachment area of the sliding door. Thereby, even further improved user-friendliness is accomplished.
- In some example embodiments, the variable-length motion actuator is a rack-and-pinion actuator. This provides a robust, cost-efficient and compact actuator solution.
- In some example embodiments, a first end of the rack is pivotally connected to the motion element and the pinion is drivingly connected to a motor and configured for being secured to the sliding door. Thereby a robust and compact assembly of the fastening arrangement is accomplished.
- In some example embodiments, the pinion is rotationally fastened on an output shaft of the motor. This results in reduced cost and improves reliability because there is no need for an external reduction gearbox.
- In some example embodiments, the rack-and-pinion actuator has a counterpressure arrangement for forcing driving engagement members of the pinion into driving engagement with corresponding driving engagement members of the rack. Thereby the operating reliability of the rack-and-pinion actuator is improved.
- In some example embodiments, the rack-and-pinion actuator has a locking arrangement providing selective locking of the rack-and-pinion actuator at a certain relative position of the rack and pinion, in particular at an extended state of the rack-and-pinion actuator. This may be relevant for ensuring that the motion element is located in the desired position upon reaching the intermediate position of the sliding door during closing of the sliding door.
- In some example embodiments, the fastening arrangement further comprises a vehicle body guiding rail that has a substantially linear guide path enabling a substantially linear movement of the motion element along the vehicle body guiding rail. The linear and straight guide rail enables improved space for propulsion battery storage in the floor of the vehicle, and/or the use of straight extruded aluminium rockers without additional manufacturing processing.
- In some example embodiments, the motion element comprises a carriage having at least two rollers for rolling engagement with the vehicle body guide rail and an attachment arrangement for pivotal connection with the variable-length motion mechanism. The pivotal connection enables improved contraction and extension motion of the variable-length motion mechanism.
- The disclosure also relates to a vehicle having a vehicle body and a sliding door, and a fastening arrangement as described above, wherein the motion element is movingly arranged within or on the vehicle body guiding rail for enabling movement of the motion element along the vehicle body guiding rail, wherein the variable-length motion mechanism is fastened to the sliding door at a lower attachment area of the sliding door, and wherein the variable-length motion mechanism enables variable distance between the motion element and the lower attachment area of the sliding door.
- In some example embodiments, the variable-length motion mechanism is a variable-length motion actuator configured for enabling powered variable distance between the motion element and the lower attachment area of the sliding door, and wherein the variable-length motion actuator is a rack-and-pinion actuator.
- In some example embodiments, the pinion is drivingly connected to a motor, and the motor is located within the sliding door. This provides a compact and robust design of the variable-length motion actuator.
- In some example embodiments, the rack has an outwardly curved shape, as seen from a top view facing downwards on the vehicle and with the sliding door in a closed position, such that a closing force vector generated by interaction of the pinion and rack, acting on the sliding door at the lower attachment area of the sliding door in a closed position of the sliding door, has a component that is directed inwards towards the vehicle body. This provides improved closure of the sliding door.
- In some example embodiments, the fastening arrangement further comprises an upper fastening arrangement providing sliding connection of the sliding door to the vehicle body between an open and a closed position of the sliding door, wherein the upper fastening arrangement includes a vehicle body upper guide rail located adjacent a vehicle body roof or roof rail and having a straight rail section and an inwardly curved rail section, an upper motion element movingly arranged within or on the vehicle body upper guiding rail, and a solid bracket connecting an upper attachment area of the sliding door to the upper motion element, wherein at a closed position of the sliding door the variable-length motion mechanism is in a contracted state and the upper motion element is located at an inner end region of the curved rail section, and wherein at an intermediate position of the sliding door the variable-length motion mechanism is in an extended state and the upper motion element is located in an outer end region of the curved rail section. The upper fastening arrangement in form of an inwardly curved guide rail ensures proper motion of the sliding door during opening and closing of the sliding door.
- In some example embodiments, the sliding door is configured for performing a first motion sequence and subsequently a second motion sequence upon moving from a closed position to an open position of the sliding door, wherein the first motion sequence involves extending the variable-length motion mechanism from a contracted state to an extended state, thereby causing the sliding door to displace from a closed position to an intermediate position while the motion element remains stationary, and the second motion sequence involves displacing the motion element along the vehicle body guiding rail, thereby causing the sliding door to displace primarily in a longitudinal direction of the vehicle body from the intermediate position to an open position of the sliding door while the variable-length motion mechanism remains in the extended state. These two motion sequences provide the desired motion of the sliding door while enabling use of straight and linear guide rails.
- In some example embodiments, the variable-length motion mechanism is a variable-length motion actuator, and the method step of performing the first motion sequence involves powered extension of the variable-length motion actuator from the contracted state to the extended state.

- Referring now to
FIGS. 1 and 2 , there is depicted a side view of anexample vehicle 1 in form of a car havingfront wheel 3,rear wheel 4,front side panel 5,front door 6,rear door 7, arear seat 17,rear quarter panel 8, atrunk door 9 and aroof 10 secured to two spaced-apart longitudinally extending roof rails. The vehicle has a horizontal longitudinal extension (straight driving direction) along an X-axis, a vertical extension along a Z-axis, and horizontal lateral extension along a Y-axis, which is perpendicular to the X-axis and Z-axis. - In the example embodiment of
FIGS. 1 and 2 , therear door 7 is configured to be a slidingdoor 7, whereinFIG. 1 shows the slidingdoor 2 in a closed position andFIG. 2 shows the slidingdoor 2 in an open position. However, the disclosure is not restricted to this specific type of vehicle. For example, the vehicle may alternatively on at least one side of the vehicle have two sliding doors opening in opposite directions and configured to jointly open and close an access opening of thevehicle 1. - The sliding
door 7 of the example embodiment ofFIGS. 1 and 2 is attached to thevehicle 1 by a fastening arrangement. The fastening arrangement fastens thevehicle sliding door 7 to a vehicle body while enabling opening and closing of the slidingdoor 7. The vehicle body generally refers to chassis of the vehicle onto which the various panels, doors, lids, etc. are attached. - In the example embodiment of
FIGS. 1 and 2 , the fastening arrangement for attaching the slidingdoor 7 to the vehicle body comprises three separate attachment arrangements that jointly cooperate for fastening the slidingdoor 7 to thevehicle 1 while allowing sliding opening and closing of the slidingdoor 7. Specifically, the fastening arrangement comprises a lower fastening arrangement located in the region of the floor androcker 11 of the vehicle body, an upper fastening arrangement located in the region of theroof 10 and a central fastening arrangement located in the region of therear quarter panel 8. - A guiding
rail 12 of the central fastening arrangement is partly shown inFIG. 1 , and an upper guidingrail 13 of the upper fastening arrangement and lower guidingrail 21 of the lower fastening arrangement are partly shown inFIG. 2 . -
FIG. 3 shows a perspective view of a lower portion of the slidingdoor 7, part of the vehicle body including therocker 11 and part of a B-pillar 16, as well part of thelower fastening arrangement 15. Therear seat 17 ofFIG. 2 is also shown inFIG. 3 . The slidingdoor 7 is in a partly opened position inFIG. 3 . - As schematically illustrated in
FIG. 3 , thelower fastening arrangement 15 may according to an example embodiment of the disclosure comprise amotion element 20 configured for being movingly arranged within or on a vehiclebody guiding rail 21 for enabling movement of themotion element 20 along the vehiclebody guiding rail 21, and a variable-length motion mechanism 22 connected to themotion element 20 and configured for being fastened to the slidingdoor 7 at a lower attachment area 23 of the slidingdoor 7. The variable-length motion mechanism 22 is configured for enabling variable distance between themotion element 20 and the lower attachment area 23 of the slidingdoor 7. - The variable-
length motion mechanism 22 is in the example embodiment ofFIG. 3 pivotally connected to themotion element 20 around a vertically extending pivoting axis at aconnection point 24. - In some example embodiments, the variable-
length motion mechanism 22 is a variable-length motion actuator 22. The variable-length motion actuator 22 is configured for enabling powered variable distance between saidconnection point 24 and the lower attachment area 23 of the slidingdoor 7. The powered variable distance of the variable-length motion actuator 22 is provided by a power source, such as for example an electric, pneumatic or hydraulic motor. Moreover, the variable distance may for example be providable also at still standing motion element. - The variable-
length motion actuator 22 may for example have a linear displacement, meaning that the variable-length motion actuator 22 provides a variable distance along a linear path. Alternatively, the variable-length motion actuator 22 may have a curved displacement, or partly curved and partly linear displacement, meaning that the variable-length motion actuator 22 provides a variable distance along a curved path, or a partly curved and partly linear path. -
FIG. 4 shows a further perspective view of the lower fastening arrangement but here with the slidingdoor 7 being removed, for the purpose of better illustrating the components and mounting of thelower fastening arrangement 15 to the vehicle body. Themotion element 20 is illustrated being a position corresponding to a partly opened position of the slidingdoor 7. - In the example embodiment of the lower fastening arrangement showed in
FIG. 4 , the variable-length motion actuator 22 is made of a rack-and-pinion actuator having arack 25 with engagement members, such as engagement teeth, and apinion 26 with corresponding engagement members, such as corresponding engagement teeth. - The
pinion 26 may for example be rotationally fastened to ashaft 27 for rotation thereof, for example by having theshaft 27 directly and indirectly connected to an output shaft of the power source. Alternatively, thepinion 26 may be rotatably mounted on astationary shaft 27 of the slidingdoor 7, and thepinion 26 is drivingly connected to a motor and configured for being secured to the slidingdoor 7. -
FIG. 4 provides a clear view of the guidingrail 21 extending along therocker 11 of the vehicle body. The vehiclebody guiding rail 21 has according to the example embodiment ofFIG. 4 a linear and straight guide path enabling a linear movement of themotion element 20 along the vehiclebody guiding rail 21 and parallel with the longitudinal direction X of the vehicle. Specifically, the guide path of the vehiclebody guiding rail 21 may according to some example embodiments, as illustrated inFIG. 4 , be linear and straight over the entire length of the guidingrail 21. - However, the guide path of the vehicle
body guiding rail 21 may alternatively be substantially linear and/or substantially parallel with the longitudinal direction X of the vehicle, wherein the term substantially linear and/or substantially parallel may include a guide path having an orientation that deviates up to 20 degrees, specifically up to 10 degrees, and more specifically up to 5 degrees between two spaced apart positions along the guide path in a horizontal plane, or wherein the term substantially linear and/or substantially parallel may include a guide path that deviates up to 10 cm, specifically up to 7 cm, and more specifically up to 4 cm from alateral edge 19 of the rocker, between two spaced apart positions along the guide path of theguide rail 21. - Such relatively small deviation from an entirely linear and straight guiding path and/or a guide path that is entirely parallel with the longitudinal direction X may in certain implementations be deemed acceptable while still not intruding any significant into a storing space of the propulsion battery or while still enabling use of straight rockers made of extruded aluminium beams.
- The vehicle
body guiding rail 21 may be an individual separate part that is configured to be attached to therocker 11 of the vehicle body. The attachment may for example be performed by welding the guidingrail 21 to the vehicle body, or by mechanical fasteners, such as rivets, threaded members, or the like. - Alternatively, the vehicle
body guiding rail 21 may formed integrally with therocker 11 of the vehicle body. An extruded aluminium rocker may for example easily be designed with an integrally formed external guidingrail 21 configured for guiding themotion element 20 along theguide rail 21. - If the vehicle
body guiding rail 21 is an individual separate part that is configured to be attached to therocker 11 of the vehicle body, an exterior laterally inwardly facing surface of the vehiclebody guiding rail 21 configured for facing 11 the rocker may be substantially planar for enabling good support to the guidingrail 21 from the vehicle body. -
FIG. 5 schematically shows a more detailed perspective view of thelower fastening arrangement 15 having themotion element 20 configured for being movingly arranged within or on a vehiclebody guiding rail 21 and the variable-length motion actuator 22, here in form of a rack and pinion actuator, connected to themotion element 20 and configured for being fastened to the slidingdoor 7 at a lower attachment area 23 of the slidingdoor 7. - In the example embodiment of
FIG. 5 , themotion element 20 comprises a carriage having at least tworollers 30 for rolling engagement with the vehiclebody guide rail 21. Themotion element 20 further comprises anattachment arrangement 31 for pivotal connection with the variable-length motion actuator 22 around a vertically extending pivotingaxis 32. - The
motion element 20 may however alternatively may composed of merely a single roller or the like, and the variable-length motion actuator may be pivotally connected to roller, such as for example to the roller axis. - A
first end 33 of therack 25 is pivotally connected to themotion element 20. Asecond end 34 of the rack, located oppositely from thefirst end 33 in a longitudinal direction of therack 25, may be free, i.e. not connected to any other part. - The rack-and-pinion actuator schematically illustrated in
FIG. 5 has arack 25 with engagement members, such as engagement teeth (not showed), and apinion 26 with corresponding engagement members, such as corresponding engagement teeth (not showed) . Thepinion 26 typically has a shape in form of a gear wheel. Therack 25 typically has an elongated straight or curved shape. - The rack and pinion actuator is a variable-
length motion actuator 22 by operating thepinion 26, i.e. making the pinion to rotate around an axis of theshaft 27 by means of the motor. This causes thepinion 26 to travel along therack 25 due to contact between the engagement members of the pinion and the corresponding engagement members of the rack, and since thepinion 26 is secured to the slidingdoor 7 at a lower attachment area of the slidingdoor 7, thepinion 26 and the slidingdoor 7 can move away or towards themotion element 20 by operation of the motor of thepinion 26. - The rack-and-pinion actuator further has a
counter-pressure arrangement 35 for forcing the engagement members of thepinion 26 into driving engagement with the corresponding engagement members of therack 25. In the example embodiment ofFIG. 5 , thecounter-pressure arrangement 35 comprises a spring-loadedcounter-wheel 36 that exerts a force on therack 25 towards thepinion 26. - The rack-and-pinion actuator may further comprise a locking arrangement for providing selective locking of the rack-and-pinion actuator at a certain relative position of the
rack 25 andpinion 26, in particular at an extended state of the rack-and-pinion actuator. InFIG. 5 , such a locking arrangement is shown in form of arecess 38 on therack 25 in the region of thesecond end 34 of therack 25, wherein therecess 38 is configured for cooperating with the counter-wheel 36 for providing a locking functionality between therack 25 andpinion 26 when the counter-wheel 36 enters therecess 38. -
FIG. 6 schematically shows a top view of the slidingdoor 7, rack-and-pinion actuator,motion element 20 and vehiclebody guiding rail 21 in a closed position of the slidingdoor 7. Thepinion 26 is thus located in its closest position to themotion element 20. Therack 25 extends in a horizontal plane and nearly parallel with the longitudinal direction X of the vehicle. -
FIG. 7 schematically shows an example embodiment of a rack-and-pinion actuator having arack 25 and apinion 26. Therack 25 has a first surface withengagement teeth 40 configured for drivingly mating withcorresponding engagement teeth 41 at the circumference of thepinion 26. Consequently, operation of the motor that causes rotation of the pinion anti-clockwise inFIG. 7 , as shown byarrow 42, will cause the pinion and sliding door to move towards the left side inFIG. 7 , as shown byarrow 45, when assuming that therack 25 remains stationary. - The rack-and-pinion actuator of
FIG. 7 further has acounter-pressure arrangement 35 in form of aframe member 43 with a spring-loadedwheel 36 that engages asecond surface 44 of therack 25, whichsecond surface 44 is located opposite to the first surface of therack 25. Since thecommon frame member 43 is connected to thepinion 26 while allowing relative rotation, the location of aspring 46 that urges theframe member 43 away from the spring-loadedwheel 36, the force of thespring 46 will simultaneously urge thepinion 26 into engagement contact with therack 25. -
FIG. 8 schematically shows an alternative design of the rack-and-pinion actuator, in which the counter-pressure arrangement is replaced with arigid securing element 47 of theframe member 43, wherein therigid securing element 47 is configured to be located closely to thesecond surface 44 of therack 25, thereby preventing thepinion 26 from leaving the engagement contact with therack 25. Therigid securing element 47 may be made of, or be lined with, a friction reducing material for enabling simplified sliding along therack 25. -
FIG. 9 schematically illustrates a top view of a cross-section of an example embodiment of theupper guide rail 13 of the upper fastening arrangement that is located at theroof 10 and/or roof rail of the vehicle body. Theupper guide rail 13 has a laterally inwardlycurved rail section 50 in a first longitudinal end region thereof, and a substantiallystraight rail section 51 extending substantially in the longitudinal direction X of the vehicle and adjacent aside edge 52 of the vehicle body at a second, opposite, longitudinal end region of theupper guide rail 13. Thestraight rail section 51 of theupper guide rail 13 is typically significantly longer than thecurved rail section 50 of theguide rail 13. As a result of the curved rail section, arecess 55 is formed in the roof and/or roof rail of the vehicle body in the region of inwardly curved portion. - The sliding door (not showed) may for example be attached to the
upper guide rail 13 by attaching the sliding door to anouter surface 56 of a solid and non-adjustable bracket 53, which may be of any shape, design or composition. The bracket 53 may be connected to the upper guide rail via anupper motion element 57. Theupper motion element 57 may be composed of merely a roller, as illustrated in the example embodiment ofFIG. 9 , or of carriage slidingly attached to theupper guide rail 13 by one or more rollers, or the like. - The bracket 53 is illustrated in three example positions along the upper guide rail in
FIG. 9 , namely a first position 54 a corresponding to a closed position of the slidingdoor 7, a second position 54 b corresponding to an intermediate position of the slidingdoor 7, and a third position 54 c corresponding to a completely open position of the slidingdoor 7. Clearly, the bracket 53 may take any position between the two end positions, which are defined by the first and third positions 54 a, 54 c, respectively. - Having the sliding
door 7 in a closed position, as shown inFIGS. 1 and 6 , involves having the rack-and-pinion actuator in a contracted state and the bracket 53 of the upper fastening arrangement being located in the first position 54 a, as shown inFIG. 9 . - Having the sliding
door 7 in a completely open position, as shown inFIG. 2 , involves having the rack-and-pinion actuator in an extended state and the bracket 53 of the upper fastening arrangement being located in the third position 54 c, as shown inFIG. 9 . - Having the sliding
door 7 in an intermediate position, involves having the rack-and-pinion actuator in an extended state and the bracket 53 of the upper fastening arrangement being located in the second position 54 b, as shown inFIG. 9 . - Upon opening the sliding
door 7 the rack-and-pinion actuator is thus first extended from the contracted state to the extended state by operation of the motor that drives thepinion 26. This extension of the rack-and-pinion actuator causes the bracket 53 to move from the first position 54 a to the second position 54 b, and the slidingdoor 7 to move from the closed position to the intermediate position. - Thereafter, an additional motor (not showed), drivingly connected to the sliding
door 7 and for example arranged adjacent the central fastening arrangement, may be controlled to pull the sliding door from the intermediate position to the completely open position. Alternatively, the slidingdoor 7 may be pushed from the intermediate position to the completely open position manually. - In other words, the fastening arrangement may comprise an upper fastening arrangement providing sliding connection of the sliding
door 4 to the vehicle body between an open and a closed position of the slidingdoor 7, wherein the upper fastening arrangement includes a vehicle bodyupper guide rail 13 located adjacent avehicle body roof 10 or roof rail and having astraight rail section 51 and an inwardlycurved rail section 50, anupper motion element 57 movingly arranged within or on the vehicle body upper guidingrail 13, and a solid bracket 53 connecting an upper attachment area of the sliding door to theupper motion element 57, wherein at a closed position of the slidingdoor 7 the variable-length motion actuator 22 is in a contracted state and theupper motion element 57 is located at an inner end region of thecurved rail section 50, wherein at an intermediate position of the sliding door the variable-length motion actuator 22 is in an extended state and theupper motion element 57 is located in an outer end region of thecurved rail section 50. -
FIGS. 10A-10C schematically shows top views of thelower fastening arrangement 15 in the three aforementioned example positions along the upper guide rail inFIG. 9 , namely the closed position of the slidingdoor 7 inFIG. 10A , the intermediate position of the slidingdoor 7 inFIG. 10B , and the completely open position of the slidingdoor 7 inFIG. 10C . - In
FIG. 10A the sliding door is in a closed position, the variable-length motion actuator 22 is in the contracted state and themotion element 20 is located in a longitudinal side portion of the guidingrail 21 associated with the closed position of the slidingdoor 7. Alateral exterior surface 60 of the sliding door is substantially flush with alateral exterior surface 61 of the vehicle. - According to one example embodiment for arriving at this position, the additional motor first pushed the sliding
door 7 in the longitudinal direction X towards the closing position of the slidingdoor 7, and upon arriving at the intermediate position the variable-length motion actuator 22 started to contract from the extended state to the contracted state. During the contraction motion of the variable-length motion actuator 22 themotion element 20 may be prevented from sliding back towards the open position of the slidingdoor 7 by for example by continued pushing force from the additional motor, or by locking motion of themotion element 20 by some type of locking arrangement. - Moreover, during the contraction motion of the variable-
length motion actuator 22 the motion path of the sliding door from the intermediate position to the closed position is controlled partly by theupper guide rail 13. However, in case also the upper fastening arrangement comprises a variable-length motion actuator connected to the motion element and configured for sliding along a substantially straight guide rail the exact motion path of the sliding door may be less foreseeable. - In
FIG. 10B the sliding door is in the intermediate position, the variable-length motion actuator 22 is in the extended state and themotion element 20 has not moved and is thus still located in a longitudinal side portion of the guidingrail 21 associated with the closed position of the slidingdoor 7. Thelateral exterior surface 60 of the sliding door is now located significantly laterally outwards beyond thelateral exterior surface 61 of the vehicle. - In
FIG. 10C the sliding door is in the completely open position, the variable-length motion actuator 22 is still in the extended state and themotion element 20 has now moved along thestraight section 51 of theupper guide rail 13 towards a longitudinal side portion of the guidingrail 21 associated with the open position of the slidingdoor 7. - In other words, the sliding
door 7 is configured for performing a first motion sequence and subsequently a second motion sequence upon moving from a closed position to an open position of the slidingdoor 7, wherein the first motion sequence involves extending the variable-length motion actuator 22 from a contracted state to an extended state, thereby causing the slidingdoor 7 to displace from a closed position to an intermediate position while themotion element 20 remains stationary, and the second motion sequence involves displacing themotion element 20 along the vehiclebody guiding rail 21, thereby causing the slidingdoor 7 to displace primarily in a longitudinal direction X of the vehicle body from the intermediate position to an open position of the slidingdoor 7 while the variable-length motion actuator 22 remains in the extended state. -
FIGS. 11A and 11B schematically shows top views of an alternative embodiment of thelower fastening arrangement 15 and the slidingdoor 7 in the intermediate position of the slidingdoor 7 inFIG. 11A and in the closed position of the slidingdoor 7 inFIG. 11B . The difference is the shape and form of therack 25, which in this example embodiment has a more curved shape. - In particular, the
rack 25 has a laterally outwardly curved shape, as seen from a top view facing downwards on the vehicle and with the slidingdoor 7 in a closed position, wherein aconvex side 66 of thecurved rack 25 faces towards the outside 67 of the vehicle and theconcave side 65 of thecurved rack 25 faces towards the inside 68 of the vehicle, in the lateral direction Y of the vehicle. - This laterally outwardly curved shape results in a
closing force vector 69, generated by interaction of thepinion 26 andrack 25 and acting on the sliding door at the lower attachment area of the sliding door in a closed position of the sliding door, that has a component that is directed laterally inwards towards the inside 68 of the vehicle body. - This inwardly directed closing
force vector 69 may in certain situations and implementations simplify closing the of the slidingdoor 7 because the slidingdoor 7 often has to move laterally inwards during the end phase of the closing sequence of the slidingdoor 7. - In the example embodiment of
FIG. 11B the closingforce vector 69 defines anangle 70 of about 30 degree with the longitudinal direction X of the vehicle. However, the closingforce vector 69 may define anangle 70 in the range of 5-70 degrees, and specifically in the range of 10-45 degrees. - The locking arrangement of the rack-and-pinion actuator was described above with reference to
FIG. 5 . This locking arrangement will now be described more in detail with reference toFIG. 12 , which shows a schematic view of the rack-and-pinion actuator in a locked state. The locking is performed by having the counter-wheel 36 becoming located in therecess 38 that is located at the region of thesecond end 34 of therack 25, wherein thespring 46 of thecounter-pressure arrangement 35 urges the counter-wheel 36 into locking engagement contact with therecess 38 of therack 25. This locking arrangement has a limited locking strength, depending on for example the spring force of thespring 46, the depth of the recess, etc. - Still an alternative example embodiment of the locking arrangement of the rack-and-pinion actuator is described with reference to
FIG. 13 , wherein anactuator 71, such as anelectromagnetic actuator 71 is configured to be secured to the slidingdoor 7 and configured to selectively control a motion of anactuator pin 72 between a locking position, as illustrated inFIG. 13 , in which thepin 72 is protruding and in engagement with theengagement teeth 40 of therack 25, for locking of relative motion of therack 25 andpinion 26, and an unlocked position, in which thepin 72 is withdrawn and not in engagement with theengagement teeth 40 of therack 25. Theactuator 71 may for example be attached to thecommon frame member 43.
