  • the present application generally relates to devices for locking and unlocking a locking pin of a vehicle component, especially of a backrest of a motor vehicle seat.

  • the locking pawl may allow an optimal flux of force and thus a high-load-bearing capacity of the device.
  • the actuating component includes an adjusting means which, when actuated, only cooperates with the locking pawl after a rotation by a safety angle, so that an inadvertent deflection of the actuating component by powerful acceleration forces, for example, by vibrations or in the event of an accident, does not lead to the adjustment of the locking pawl into the release position.

  • the locking hook 1 In the locked position, the locking hook 1 cooperates positively and/or non-positively with the locking pawl 2 , so that the locking hook 1 is secured in the locked position.
  • An actuating component 4 is rotated by actuating an actuating means 6 .

  • Force means 5 in this case a (tension) spring, includes a first end 51 provided on the actuating component 4 and a second end 52 provided on the locking hook 1 .
  • the force provided by force means 5 may pull the locking hook 1 along the contour 20 of the locking pawl 2 into the unlocked position.
  • the locking hook 1 , the locking pawl 2 , as well as the actuating component 4 are arranged rotatably on a base plate 3 .
  • the locking hook 1 bears with a second stop 14 against the base plate 3 .
  • the locking hook 1 includes a first stop 13 which occasionally bears, in the locked position, against the base plate 3 .
  • the arrangement shown of the locking hook 1 and locking pawl 2 may allow a good flux of force and thus high load bearing, especially in the event of an accident.
  • the arrangement may also provide for good tolerance compensation. For example, a tolerance compensation in the range of approximately +/ ⁇ 3 mm and +/ ⁇ 7 mm is possible.
  • the arrangement is robust relative to its crash behavior, especially with regard to multidirectional acceleration.
  • the mass of the actuating component 4 is evenly distributed and the actuating component is substantially disk-shaped, so that the actuating component 4 is relatively insensitive to lateral force acceleration. Moreover, the actuating component 4 is adjusted to the locking pawl 2 such that the actuating component 4 releases the locking pawl 2 by means of the slot 9 only after rotating past a safety angle which preferably is 2°-15°. Thus, it is ensured that sufficiently idle stroke range is present so that the locking pawl 2 does not release the locking hook 1 inadvertently, for example, due to a large load, in particular, in the event of a crash. Mass balanced and disk-shaped actuating component 4 may also be relatively insensitive to multidirectional acceleration and thus may ensure a secure locking of the locking hook 1 in the locked position.
  • the lightly pretensioned spring 5 is further tensioned and pulls the locking hook 1 along the contour 20 of the locking pawl 2 into the unlocked position.
  • the contour of the locking hook 1 may correspond to the contour 20 of the locking pawl 2 so that the locking pawl 2 maintains its release position when locking hook 1 is in the unlocked position and when the locking hook 1 is rotated from the unlocked position into the locked position.
  • the spring 5 couples the locking hook 1 to the actuating component 4 .
  • the locking pawl is, however, not spring-loaded.
  • the rotation of the locking hook 1 from the unlocked position into the locked position is thus possible independent of the securing of the locking hook 1 by means of the locking pawl 2 , i.e. independent of the rotation of the locking pawl 2 from the release position into the secured position, and thus also independent of the rotation of the actuating component 4 .
  • the locking hook thus remains, however, unsecured.

  • the sliding element 10 is made at least partially from a plastics material, and spring-loaded by means of a second force means 16 .
  • the clearance between the locking hook 1 located in the locked position and the locking pin 8 is reduced. This clearance reduction may result in a device that is relatively quiet and does not rattle.
  • a steel spring may be used as the second force means 16 , as the force of a steel spring is substantially independent of the ambient temperature when compared with conventionally used rubber elements.
  • the sliding element 10 at least in the region of the locking pin 8 , is made from a plastics material to avoid unpleasant noise generation, especially by the friction of steel against steel.
  • the spring path of the second force means may be short (e.g., approximately 1-5 mm).
  • the spring path of the second force means is preferably approximately 3 mm. A short spring path may allow the locking to be carried out relatively easily for the user.

  • the terms “device” and “backrest lock” as well as the terms “further device” and “torque block” may hereinafter be treated synonymously. Views a-c only show the actuating means 6 schematically.
  • View a shows a sectional view of the backrest lock and the torque block in the center bearing in the unlocked state of the backrest lock and in the unlocked state 180 of the torque block.
  • the display means 11 signals an insecurely locked backrest.
  • View b shows a sectional view of the backrest lock and the torque block in the center bearing in the locked state of the backrest lock and in the unlocked state 180 of the torque block.
  • the display means 11 signals an insecurely locked backrest.
  • View c shows a sectional view of the backrest lock and the torque block in the center bearing in the locked state of the backrest lock and in the locked state of the torque block 180 .
  • the display means 11 signals a securely locked backrest.
  • the signaling means 7 of the backrest lock receives the locking state of the torque block as a mechanical signal SI.
  • the signal is transmitted by means of a flexurally stiff Bowden cable 18 which is arranged on the signaling means 7 .
  • the signaling means 7 is connected to the display means 11 by means of a connecting rod 19 .
  • the flexurally stiff Bowden cable 18 thus prevents the signaling means 7 from being rotated and/or the locking pawl 2 from being rotated from the release position F into the secured position S. Due to the connecting rod 19 , it is displayed on the display means 11 that the backrest is not completely locked.
