Definitions
- the invention relates to vehicle door locks.
- the locks of a vehicle opening usually include a large number of parts including to control the opening of the opening both from outside the vehicle than from the inside.
- each of the outer and inner handles is able to control the rotation of the same intermediate lever which bears against a false pawl which drives a pawl which itself releases the bolt, which is released from the latch , thus releasing the opening.
- An object of the invention is to improve the comfort of the user when controlling the opening of the opening.
- the invention provides a system for opening a vehicle, characterized in that it comprises:
- the system being arranged such that a distance between a first geometrical line passing through the contact zone between the lever and the rotary member and normal to this contact zone and a second geometrical straight line parallel to the first straight line and passing through the axis of rotation of the lever is evolving in a constant direction of growth or decay during the entire opening movement of the opening.
- the lever and the member are shaped so that, upon opening, they are in mutual contact by profiled faces having generatrices parallel to each other.
- the member comprises a support and a roller rotatably mounted relative to the support and adapted to roll against the lever.
- the contact between the two elements generates only a rolling friction, which reduces the effort to be provided by the user for the opening of the opening.
- the lever has a ramp face along which the contact zone moves during opening
- the ramp face has a profile of curved shape
- the ramp face has a profile whose radius of curvature narrows on a section traversed by the member during opening;
- the ramp face has an elliptical and / or concave profile
- the member comprises a false pawl
- At least one of the control parts comprises a rotatably mounted lever.
- FIG. 1 is a perspective view of a part of a lock according to a embodiment of the invention.
- Figure 2 is a diagram of the kinematic chain of the parts of the lock of Figure 1;
- Figures 3 and 4 are two plan views of the intermediate lever and the false ratchet of the lock of Figure 1, respectively at the beginning of the opening maneuver and at the end of the latter;
- Figure 5 is a general curve of the evolution of the effort provided by the user according to the stroke of the handle during the opening maneuver.
- Figure 6 is a view similar to Figure 5 illustrating this evolution during the operation of the false pawl by the lever.
- FIG. 1 a system for an opening 22 of a motor vehicle according to one embodiment of the invention.
- the opening is for example a door.
- Some parts of the lock mentioned below are of a conventional type and are not described in detail and / or illustrated.
- EP-1 158 124 for more details on certain aspects of the lock, reference may be made to EP-1 158 124 in the name of the applicant.
- the system comprises the following members which are arranged to maneuver each other successively in the order in which they are mentioned below, for the transmission of an opening command of the opening leaf, thus forming a kinematic chain:
- the handle 4 is rotatably mounted relative to a frame 20 of the opening 22. It actuates, via the cable 6, the inner opening lever 8 which is rotatably mounted. The latter actuates the intermediate opening lever 10 which is also rotatably mounted relative to the frame 20 about an axis 24, the false pawl 12 and the pawl 14 are rotatably mounted relative to the frame 20 around the same axis 26, but are movable relative to each other.
- the axes 24 and 26 are distant and parallel to each other.
- the system also comprises the following members which are arranged to maneuver each other successively in the order in which they are mentioned below, for the transmission of an opening command of the opening, thereby forming a kinematic chain:
- the outer handle 30 is fixed to one end of the cable 32 whose other end is fixed to the outer opening lever 34.
- the latter is rotatably mounted and can maneuver the clutch lever 36.
- a clutch 38 is interposed in the drive train between the clutch lever 36 and the intermediate opening lever 10.
- the clutch 38 can assume an engaged configuration in which it allows the intermediate lever 10 to be operated by means of the clutch lever 36 or a clutch lever 36. disengaged configuration in which the clutch lever is unable to maneuver the intermediate lever.
- the kinematic chain portions ranging from elements 4 to 8 on the one hand and 30 to 36 on the other hand are distinct and independent of each other. They allow each, independently of one another, to operate the intermediate opening lever 10 to release the pawl 14 of the bolt 16 and release the striker 18 and thus open the opening. When it is a maneuver from the handle 30, it assumes that the clutch 38 is engaged.
- the false pawl 12 comprises a main support 40 and a roller 42 having an outer face 43 of cylindrical shape with circular section in a plane perpendicular to the axis 24.
- the roller is rotatably mounted on the support 40 about an axis 44 distant from the axes 24 and 26 and parallel to them.
- the intermediate lever 10 has a profiled side face 46 forming a rolling ramp for the roller 42.
- This face has a generally cylindrical shape but the section of its profile is not circular. In this case, this cylindrical face has generatrices parallel to the axis 44 and the generatrices of the face 43 of the roller 42.
- the face 46 has in this case a profile of curved shape, concave and forming a portion of ellipse .
- the face 46 On the section of this face traversed by the roller as will be seen in the following, the face 46 has a radius of curvature which is narrowing in the direction of travel of the roller during opening.
- the lock operates as follows with respect to the false pawl and intermediate lever.
- FIG. 5 illustrates the general curve of the intensity of the force provided by the user on one of the handles 4, 30 to open the opening, as a function of the stroke of the handle.
- the next section 52 corresponds to the phase of the movement during which the intermediate lever 10 operates the false pawl 12. Knowing that the roller rolls against the lever 10, the force exerted by the latter on the false pawl is essentially reduced to its component perpendicular to the tangent to the contact faces.
- the zone of contact between the roller 42 and the face 46 is at a distance d1 of approximately 10 mm from the axis 24, when this distance is measured tangentially. at the face 46 at the point of contact with the roller.
- Such a distance d1 is measured between a first geometrical line passing through the contact zone and normal to it and a second geometrical straight line parallel to the first straight line and this time passing through the axis of rotation of the lever. We will see below that this distance is growing as the opening of the opening.
- the distance d1 thus measured is the lateral distance from the axis of the feedback force between the roller and the lever relative to the axis 24 of the lever.
- the roller 42 rolls against the ramp face 46 to the position shown in Figure 4.
- the contact zone between the roller and the lever 10 is at a distance d2, measured in the same way as previously , for example about 14 mm, of the axis 24 which is greater than the distance d1.
- the force exerted by the latter on the false pawl is essentially reduced to its component perpendicular to the tangent to the contact faces.
- the zone of contact between the roller 42 and the face 46 is at a distance d2 of about 14 mm from the axis 24, when this distance d2 is measured tangentially to the face 46. at the point of contact with the roller.
- the user feels increasing resistance on the handle throughout the movement of manual operation of the handle, resulting in an improved feeling for the latter.
- Such an improved feeling is particularly the absence of upward and downward variations which then tends to give the user a feeling of inappropriate mechanical succession during the movement.
- the ramp face 46 is conformed so that the lever arm decreases over the entire opening movement of the ramp.
- the user then perceives resistance to movement without successive variations upward then downward.
- Such decreasing resistance is obtained in particular with a ramp 46 of convex shape, according to a curvature adapted to a decrease of the lever lever measured in the same manner as explained above.
- the distance d2 thus measured is again the lateral distance from the axis of the feedback force between the roller and the lever relative to the axis 24 of the lever.
- the lock is such that the bolt is released from the striker, which causes a drop in the intensity of the force on the last section 54.
- FIG. 6 illustrates in greater detail a curve 56 derived from readings Experimental corresponding to the section 52 and a line 58 indicating the general trend. This line is slightly inclined relative to the horizontal direction, meaning that the rise in effort is relatively slow during this phase.
- the straight line 58 corresponds to a substantially linear increase in the distance d, illustrated under the references d1 and d2 above, during the opening operation of the lock. Such linear progression 58 is achieved by the profile of the face 46 according to the present embodiment.
