Abstract
Description
Technical Field
[0001] The present invention relates to a vehicle equipment component comprising a base component and a component movable relative to the base. The movable component can be locked in at least one position relative to the base by means of a locking device. Background Art
[0002] For example, a vehicle equipment component is formed by a headrest. A headrest is known from prior art publications, which includes a base supported on a retaining device and a headrest component movable in the x-direction toward the head of a seat occupant and in the opposite direction, the headrest component forming a movable component that is movably supported relative to the base.
[0003] The movable component can be locked in a plurality of positions by means of a locking device. The locking device comprises a plurality of locking structures formed on the headrest component, which cooperate with a movable latch. The latch is movable between a locked position and a released position. In the locked position, the latch engages with the locking structures, and in the released position, the latch is out of engagement with the locking structures.
[0004] The latch must have sufficient clearance with respect to the locking structure in order to enable movement between the locked position and the released position. Disadvantageously, the clearance between the latch and the headrest component results in undesirable noise. Summary of the Invention
[0005] The object of the present invention is to provide an equipment part which, in the locked position, avoids play between the locking bar and the movable part.
[0006] This object is achieved by an equipment component according to the invention.
[0007] The equipment component is configured for a vehicle. A vehicle is defined as a land vehicle, aircraft, or ship. The equipment component comprises a base and a component movable relative to the base. The movable component can, for example, move translationally or rotationally, or have a mixed movement including translational and rotational components.
[0008] The movable part can be locked relative to the base in at least one position by means of a locking device. "Lockable" within the meaning of the present invention means that the movable part cannot be moved in at least one direction of movement in the locked position of the locking device.
[0009] The locking device is movable between a locked position and a released position. In the locked position, movement of the movable component in at least one direction is not possible. In other words, movement is not possible only in one direction of movement or in two opposite directions of movement.
[0010] The locking device comprises at least one locking structure in the form of a recess, in which recess at least one locking bolt engages in a locked position of the locking device and is disengaged from the recess in a released position.
[0011] According to the present invention, the locking device comprises a safety latch and at least one comfort latch, the safety latch having at least one first locking surface that cooperates with the first retaining surface of the cutout, and the comfort latch having a second locking surface that cooperates with the second retaining surface of the cutout. The second locking surface is inclined relative to the first locking surface.
[0012] Since the second holding surface is inclined relative to the first holding surface, the locking bar can be moved into the recess to such an extent that the locking bar not only abuts against the first locking bar but is also in contact with the second holding surface. Thus, the gap can be completely eliminated.
[0013] The inclination is, for example, so great that the cooperating surfaces of the comfort latch and the movable part are outside the self-locking state. Thus, for example, it is possible to first move the second latch from the primary position into the secondary position in order to move the comfort latch out of engagement with the second retaining surface. The safety latch, which is no longer loaded by the comfort latch on the first retaining surface, can then be moved out of the recess.
[0014] At least one of the retaining surfaces extends, for example, approximately at right angles to the direction of movement of the movable component. If the safety latch has a blocking surface extending approximately parallel to this surface, movement in one of the directions of movement can be reliably blocked if this surface cooperates with the latch. Thus, for example, when the movable component is loaded in the direction of movement x2, no forces act to move the latch in the release direction.
[0015] Preferably, the retaining surface directed toward the impact force is formed approximately at a right angle to the direction of movement of the movable component.
[0016] When the inclined locking surface cooperates with the retaining surface of the cutout, the resulting force when a force is applied by the movable element can force the latch out of engagement with the cutout. By means of a locking element that blocks the movement of the latch in the release direction, for example, unintentional unlocking can be prevented.
[0017] The first blocking surface is arranged, for example, opposite to the second blocking surface. In this way, the movement of the movable component in two opposite directions can be prevented.
[0018] The first retaining surface and / or the second retaining surface extend approximately at a right angle to the direction of movement of the movable component. If the locking surface cooperating with the respective retaining surface extends parallel to the retaining surface, no force can be generated that would load the latch out of the engagement with the recess.
[0019] Described safety latch for example has at least one first blocking surface parallel to first holding surface.If the first holding surface is parallel to the first blocking surface structure when force impacts on the movable part, then do not load the safety slide in the disengaging direction.
[0020] For example, the second holding surface is inclined relative to the first holding surface. The inclination is, for example, such that the recess is open for easier insertion of the comfort latch.
[0021] At least one of the safety latch and the comfort latch is designed, for example, as a slide. In particular, both latches are designed as slides. Each slide is supported for translational movement. At least one slide is supported, for example, on a base. In this case, guidance is relatively inexpensive. Furthermore, the space required by the slide is very small. High locking forces can be transmitted by means of the slide.
[0022] Alternatively, however, the at least one locking bar can also be rotatably mounted or mounted in such a way that it executes a mixed movement having a translational and a rotational component.
[0023] The safety latch and the comfort latch can for example be supported relative to each other in a relatively movable manner. In this way, a latch can (at least in a limited range of motion) move out of the engagement with the holding surface independently of another latch.
[0024] One of the safety latch and the comfort latch is supported on the other latch, for example. In particular, the comfort latch is supported on the safety latch. With this embodiment, a compact structure can be achieved.
[0025] One of the safety latch and the comfort latch for example has a first stop face and a second stop face, and the end position of the other latch is defined by the stop face. So one latch can be guided on the other latch with limited movement clearance.
[0026] One of the safety latch and the comfort latch can, for example, have a driving element. This makes it possible that when one latch moves, the other latch is driven along. The driving can, for example, be staggered so that one latch travels a certain distance relative to the other latch before the other latch is driven along.
[0027] Described safety latch and described comfort latch are for example guided on described base.In this way, the high force that acts on the latch can be accepted by the base directly or indirectly.
[0028] The safety latch is for example loaded into the locked position by a spring in a manner that engages with the first holding surface. When the safety latch moves into the release position, the locked position of the locking device is automatically re-established.
[0029] The comfort latch is urged into engagement with the second retaining surface, for example, by a comfort spring, or alternatively, into a defined position relative to the safety latch. If the comfort latch has a separate guide, for example, independent of the safety latch, the spring can urge the comfort latch into engagement with the second retaining surface. If the comfort latch is guided on the safety latch, for example, it can be urged into a defined relative position relative to the safety latch. This position can be, for example, an end position in which the comfort latch rests against the safety latch.
[0030] The safety latch and / or the comfort latch can be moved between two positions by means of an actuating device. For example, the actuating device moves the two latches separately. Alternatively, for example, the actuating device can move one of the latches during actuation, which then entrains the other latch after a certain distance. For example, the comfort latch is first moved out of engagement with the second retaining surface, and then the safety latch is moved into the disengaged position. In this case, the movement of the safety latch can be performed relatively easily, so that the safety latch is not forced into contact with the first retaining surface by the comfort latch.

[0050] The equipment component is generally indicated in the drawings by the reference numeral 10. In the present embodiment, the equipment component 10 is a headrest.
[0051] Equipment component 10 according to Figure 1 and Figure 2 The headrest comprises a base 11 and a component 12 movable relative to the base 11. In this case, the movable component is a headrest device movable relative to the base 11 along directions x1 and x2, and having a headrest surface 21. The base 11 is held on a holding device 22.
[0052] The movable part 12 is Figure 3 and Figure 4 The first position shown in Figure 5 and Figure 6 and a second position shown in FIG.
[0053] according to Figures 3 to 6 The equipment component 10 includes a locking device 20. The locking device 20 includes a plurality of cutouts 13 arranged one after another along the movement directions x1 and x2 so that the movable component 12 can be locked in a plurality of positions on its movement path. In this embodiment, the movable component 12 can be locked in a first position, a second position, and a plurality of intermediate positions between the first and second positions.
[0054] The cutouts are provided on the projections 19, which extend in the direction x2 relative to the headrest surface 21 of the movable component 12. Each of the cutouts 13 has a first retaining surface 34 parallel to the directions of movement z1 and z2, and a second retaining surface 35 lying opposite the first retaining surface 34 and inclined to the directions of movement z1 and z2.
[0055] The locking device 20 also includes a locking assembly 15 having a safety latch 14 and a comfort latch 16. The safety latch 14 prevents the movable part 12 from being unintentionally moved out of the adjusted position in the directions x1 or x2. The comfort latch 16 prevents play between the movable part 12 and the safety latch, and thus between the movable part 12 and the base 11.
[0056] The safety latch 14 is designed as a slide and is movable in a guide (not shown further) of the base 11 between a locked position and a released position in directions z1 and z2. The comfort latch 16 is designed as a slide and is supported on a guide rail formed on the safety latch 14. The comfort latch 16 is movable relative to the safety latch 14 between a primary position and a secondary position in directions z1 and z2. The primary position is, for example, Figure 3 As shown in the figure, the secondary position is Figure 4 Shown in.
[0057] Safety spring 17 (see Figure 7 and Figure 8 ) The safety latch 14 is loaded in the direction z1 into the locked position, i.e., into engagement with one of the recesses 13. The safety latch 14 is thus automatically moved into the locked position. The safety spring 17 is supported on the base 11 and on the arm 23 of the safety latch 14.
[0058] The comfort spring 16 forces the comfort latch 16 into the primary position. The comfort spring 18 is supported on the safety latch 14 and the comfort latch 16. To this end, the comfort latch 16 has an arm 24 and the safety slide has an arm 25, with which the comfort spring 18 is in contact and forces them in opposite directions z1 and z2.
[0059] exist Figure 7 It can be seen that the comfort latch 16 is slidably guided on the safety latch 14. In the present example, the safety latch 14 has a guide groove 26, in which the plate-shaped comfort latch 16 is guided movably in the direction z1 and z2 in a drawer-like manner.
[0060] exist Figure 7 and Figure 8 It can be seen that the safety latch 14 has a locking area 28 and the comfort latch 16 has a locking area 29. The safety latch 14 is provided with a recess 27 in which the locking area 29, which projects relative to the outer surface of the safety latch 14, is displaceable. The safety latch 14 is configured with a first locking surface 31 that is approximately parallel to the directions of movement z1 and z2, while a second locking surface 32 is configured on the locking area 29, which is inclined relative to the first locking surface 31. This inclination is such that the locking area 29 widens at right angles to the Z axis in the direction of movement z1 of the comfort latch 16.
[0061] The first blocking surface 31 of the locking bar 14 interacts with the first retaining surface 34 and the second blocking surface 32 of the locking bar 16 interacts with the second retaining surface 35 .
[0062] In accordance with Figures 9 to 11In the locked position, the first retaining surface 34 is in contact with the first locking surface 31. Furthermore, the second retaining surface 35 is in contact with the second locking surface 32. Since the second locking surface 32 is loaded against the second retaining surface 35 by the comfort spring 18, no gap is formed between the safety latch 13, the comfort latch 14, and the recess 13.
[0063] exist Figure 9 1 shows a rear view of the equipment part 10. It can be seen that the two projections 19 of the movable part 12 are guided in the recesses 41 of the base 11. In order to avoid high friction resistance, projections 39 are formed on the guide surface 38.
[0064] In addition, according to Figure 10 The locking device 20 has an actuating device 30. The actuating device 30 includes an actuating element 33, which is guided on the base 11 so as to be movable in directions y1 and y2 between an unactuated position and an actuated position. The actuating element 33 is biased into the unactuated position by a spring 45. The actuating element 33 includes an actuating shoulder 42, which cooperates with a starter element 43, which is designed as a plane inclined in the direction of movement, to move the comfort latch 16 into the released position and the safety latch 14 into the disengaged position.
[0065] according to Figure 12 The stop surface 36 of the comfort latch 16 is at a distance l from the bottom surface 37 of the safety latch 14 .
[0066] The comfort latch 16 can therefore be moved in the direction z2 relative to the safety latch 14 .
[0067] A further stop surface 49 of the safety latch 14 interacts with the stop surface 48 of the comfort latch 16 and defines a first position of the comfort latch 16 (see Figure 12 ).
[0068] The actuating element 33 includes a locking element 44, which is part of the safety device 40. The locking element 44 prevents the safety latch 14 from being unintentionally moved into the disengaged position (e.g. due to inertial forces) against the force of the safety spring 17. The locking element 44 cooperates with a bottom surface 46 of the safety latch 14.
[0069] In accordance with Figures 9 to 11 In the unactuated position of the actuating device 30 , the actuating shoulder 42 is located relative to the actuating element 43 in such a way that no actuation occurs.
[0070] If the operating element 33 moves in the direction y1 (see Figure 12 and Figure 13), the locking element 44 is also displaced in the direction y1. Furthermore, the actuating shoulder 42 comes into contact with the starting element 43 and thereby loads the comfort latch 16 in the direction z2. The actuating shoulder 42 and the starting element 43 form a motion converter that converts the force applied by the actuating part 33 in the direction y1 into a force acting on the comfort latch 16 in the direction z2 (see Figure 12 ).
[0071] Here, the comfort latch 16 moves relative to the safety latch 14 in the direction z2 by a length l, and the second closing surface 32 loses contact with the second retaining surface 35 of the recess 13 (see Figure 13 ). The stop surface 36 of the comfort latch 16 is moved into contact with the bottom surface 37 of the safety latch 14. The comfort latch 16 is then in the second position.
[0072] When the operating part 33 moves further in the direction y1 (see Figure 14 and Figure 15 ), the safety slide 14 is entrained by the comfort slide 16 in the direction z2. The locking element 44 is displaced in the direction y1 to such an extent that it is no longer in the movement path of the safety latch 14. The locking areas 28 and 29 are completely moved out of the recess 13. The locking surface 31 is then no longer in contact with the retaining surface 34.
[0073] The movable part 12 can then be moved, for example, from Figure 3 The first position moves to the Figure 4 in the second position or in a position therebetween.
[0074] If the operating part 33 is unloaded, the spring 45 moves the operating part 33 in the direction y2 into the unactuated position and also moves the operating collar 42 in the direction y2 relative to the starting element 43. Due to the spring force of the safety spring 17, the safety slide 14 and the comfort slide first move together in the direction z1.
[0075] If the safety latch 14 has reached the locked position, the comfort latch 16 is moved further relative to the safety latch 14 due to the spring force of the spring 18 in the direction z1 into the primary position in which the second locking surface 32 is in contact with the second retaining surface 35 .
[0076] In the unactuated position of the actuating part 33 , the locking element 44 is again located relative to the safety latch 14 such that a movement of the safety latch 14 in the direction z2 is blocked by the locking element 44 . The locking surface 47 is arranged in the movement path of the bottom surface 46 .
