Definitions
- the invention relates to a device according to the preamble of claim 1.
- a number of possibilities for solving this problem have become known, such as a net-like collecting element located in front of the windshield or an airbag in the transition area between the windshield and the front window, which is sensor-controlled inflatable in the event of an impact.
- DE 28 14 107 A in conjunction with DE 28 41 315 shows another solution principle for reducing the risk of injury when people collide with the front hood, based on the consideration is based on substantially mitigating the relatively hard and unyielding impact area located in the rear area of the front hood facing away from the direction of travel.
- This is brought about by a device actuated by means of an impact sensor for adjusting the front hood from a rest position into a resilient impact position which is raised in comparison therewith, ie by a so-called “active front hood”.
- active front hood The fact that the front hood in the case of which the impact sensor detects If a collision with a person is resiliently adjusted in relation to his or her rest position, i.e.
- This known construction is based on the idea that the hinge arrangement itself with the hinged hinge bracket in relation to the body, so that it is not necessary to provide a complex decoupling device between the hinge arrangement and the bonnet in the event of an impact.
- the invention also proceeds from this construction principle.
- the hinge bracket which forms the base plate for the hinge arrangement, is articulated at its front end section via an axis of rotation on a screw-on plate to the support bracket for the front fender.
- the hinge bracket is locked by means of a sensor-controlled locking device with an eccentrically mounted bolt.
- an energy-storing device preferably a prestressed leg spring, articulates on the hinge bracket.
- the locking device is released and the hinge bracket is released.
- the pretensioned leg spring the latter swings upward rapidly around the axis of rotation and lifts the front hood together with the hinge arrangement by a predetermined angle.
- the hinge bracket is set up by a guide in the event of a collision without pivot bearing by a limited stroke.
- the hinge support is seated on two curved guide arms.
- Cylinder unit is provided, which is connected to the hinge bracket via a force-diverting intermediate element.
- the invention is based on the object of designing the device described at the outset for protecting people in the event of a frontal impact on a motor vehicle in such a way that no deflection of force is required when the front hood is installed by means of a spring accumulator, and also a very compact and relatively simple structure of the protective Device can be achieved.
- a device for protecting people in the event of a frontal impact on a motor vehicle which has a front hood covering the front end, which is anchored on both sides of the windshield on each side of the vehicle via a hinge arrangement and rotatably anchored to the body of the front end, each with a Sehami strap which the hinge arrangement is articulated on the body side and which can be set up on the body of the front end, with a spring-loaded arrangement for setting up the hinge support and with a release and holding device with a sensor-controlled actuator, which is designed so that in the basic state the Hinge bracket is held down and, in the event of a collision, sensor-activated for a limited set-up movement (working stroke) can be released by raising the front hood in the hinge area, in accordance with the invention in that the device has an elongated housing that can be attached to the vehicle and has a top that can be set up linearly and to which either the hinge bracket is attached is or that directly forms the hinge bracket that two pivot levers are provided, which
- the hinge support of the lever-mounting device according to the invention which can be set up in a linear manner, ensures a uniform and thus secure installation of the hinge support.
- the simple construction of the lever stand enables a simple, inexpensive construction of the device.
- Embodiments of the invention are characterized in the subclaims and also result from the description of the figures.
- the invention is described in more detail with reference to three exemplary embodiments shown in the drawings in different views and states.
- FIG. 1 is an isometric view of a first embodiment of the swivel lever installation device according to the invention for a hinge bracket in the retracted basic state
- FIG. 2 shows the device according to FIG. 1 in a retracted basic state in a longitudinal section
- FIG. 3 is an isometric view of the erection device of FIG. 1 in the triggered, erected state
- FIG. 4 in a longitudinal sectional view, the device of FIG. 3 also in the extended state
- FIG. 5 shows a horizontal section through the device according to FIG. 6,
- FIG. 6 shows a schematic vertical longitudinal sectional view of a second embodiment with synchronization of the raising movement of the pivoting levers by gearwheels, with symmetrical pivoting levers,
- FIG. 7 shows a horizontal section through the device according to FIG. 8,
- Fig. 8 jn a schematic longitudinal section view of a third embodiment with synchronized pivot levers analogous to FIG. 6, but with asymmetrical pivot levers.
- the inventive device for protecting people in the event of a front impact on a motor vehicle is based on the principle that in the event of a collision with the person the windshield side of the motor vehicle, including its hinge arrangement, which is attached via a hinge arrangement, is set up in the stop area by a predetermined stroke relative to the body of the front end.
- the device initially has a substantially rectangular housing 1, which contains the sensor-controlled components for the active installation of the front hood, and which is fastened in a conventional manner to the body of the front end in the area of the hinge arrangements, preferably to the support bracket of the fender. Such a device is attached to both sides of the front end.
- the housing consists of three telescopically nested housing parts, a lower part 1a forming the housing base with side walls, which is firmly attached on the body side, a displaceable central part 1b for extending the side walls and one with the housing cover Side walls forming, also movable upper part 1c.
- the individual housing parts typically have corresponding guides on the end faces in order to ensure that the middle and upper part are set up safely and without tilting.
- the upper part 1 c has a substantially rectangular plate 2 on the head side, hereinafter referred to as a stand-up plate.
- the associated hinge assembly for the front hood for. B. a 4-joint hinge, attached to the body in a known manner.
- a Hinge flange is provided on which the two upper joints of the hinge rods are articulated.
- the base plate can also be designed directly as a hinge bracket.
- the hinge bracket is set up in the same way and also the hinge arrangement with the rear part of the front hood.
- the hinge bracket with the associated hinge arrangement and the front hood of the car are not shown for the sake of simplicity.
- bearing bolts 3, 4 are fixedly attached parallel to one another on the longitudinal side walls in the region of the end faces.
- a pivot lever 5, 6 is rotatably mounted on each of these bearing bolts.
- a set-up leg spring 7, 8 with high spring force is applied to each of these bearing bolts, one leg of which is clamped fixed to the housing and the other leg engages around the associated pivoting lever, which braces it in the erecting sense.
- the free end of the equally long, intersecting pivot levers 5, 6 is each provided with a guide bolt 9, 10, which is received in guide tracks 11, 12.
- the guide pins are in lower extensions 13a, 13b of a carrier plate 13, which in turn is attached to the underside of the ufstelipiatte 2. This support plate can be omitted if the base plate is dimensioned accordingly stronger.
- a sensor-controlled pyrotechnic actuator 14 with one in the activated state ejected pin 14a firmly attached, and a two-armed holding pawl 15, which is biased by a holding leg spring 16 in the holding sense, pivoted.
- the upper arm, the holding arm, the holding pawl 15 is in releasable operative engagement with a holding claw 17, on the extension 13a, while the lower arm, the control arm, is in operative contact with the pin 14a of the actuator 14.
- a threaded sleeve 18 is fixedly attached to the housing base above a corresponding opening for the reversal of the system that is still to be explained.
- the actuator 14 If the actuator 14 is triggered, it ejects the pin 14a, which rotates the holding pawl 15 against the spring force of the holding leg spring 16. As a result, the active engagement between the holding pawl 15 and the holding claw 17 is canceled. Under the great bias of the strong splitting leg springs 7, 8, the swivel levers 5, 6 rotate on -fste-liejid .--- Thereby, the guide bolts 9, 10 slide on the swivel lever ends into the sliding guides 11, 12 of the carrier plate and thus the housing upper part 1 c.
- the reversing is carried out using a reversing rod with a threaded section, which is mounted through the opening 2a in the mounting plate 2 into the threaded sleeve 18 and abuts the mounting plate with an annular shoulder. It is screwed in until the active engagement between the holding pawl 15 and the holding claw 17 is restored. The reversing rod is then removed. This reversing is carried out in steps alternately on the two set-up devices.
- Swivel lever is provided. Insofar as the components are functionally identical to those in FIGS. 1 to 4, they were the same
- the two pivot levers 5, 6 are rotatably mounted in alignment in the center of the housing on two bearing bolts 3, 4 arranged in parallel in the lower part 1a. These have swivel levers in the storage area Gears 19, 20 which mesh with one another in the assembled state and thus ensure a synchronous rotary movement.
- the pivot levers 5, 6 are each preloaded with a double split leg spring 7, 8, between which the assigned pivot lever is located, in the basic state of the system.
- Both swivel levers each have a permanently mounted guide pin 9, 10 on the upper arm, these guide pins, as in the case of the first exemplary embodiment, slidingly moving in slot holes 11, 12, which are formed in extensions 13a, 13b of the upper housing part 1c that can be set up.
- a retaining claw 17 is integrally formed on the extension 13a, into which a spring-loaded retaining pawl 15, which is rotatably articulated in the lower part 1a, interlockingly engages in the tensioned state of the system.
- the actuator 14 If the actuator 14 is triggered, it ejects a pin which pivots the holding pawl 15 against the force of the holding leg spring 16 and thereby releases the holding claw 17.
- the two double set-up leg springs 7, 8 can pivot the pivoting levers 5, 6 in synchronous movement, the housing upper part 1 c being carried along via the guide pins 9, 10 and the extensions 13a, 13b of the carrier plate.
- the set-up state is shown in broken lines in FIG. 6.
- the housing 1 can be made not only in three parts as in the case of FIGS. 1 to 4 or not only in two parts as in the case of the embodiment in accordance with FIGS. 5 to 8 but also in one part, with a mounting plate which forms the cover of the housing and has additional guides , and on which the extensions 13a, b are attached.
- the holding / triggering system 14 to 17 can also be designed differently, e.g. B. Instead of the holding claw 17, it can have a holding bolt which is encompassed by a rotary pawl. Instead of the pyrotechnic actuator, a trigger magnet that can be activated by the vehicle electrical system can also be provided, and reversing can also be carried out in another way.
