Abstract
An adjusting mechanism includes a first sub-assembly, a bolt disposed on the first sub-assembly and a second sub-assembly. The bolt is configured to receive a force in a radial direction relative to an axis of the bolt. The second sub-assembly is mounted so as to be rotatable relative to the first sub-assembly by means of the bolt. The rotatability of the second sub-assembly relative to the first sub-assembly is configured to be reduced by a positive connection created using plastic deformation between the bolt and at least one of the first sub-assembly and the second sub-assembly.
Claims18
An adjusting mechanism comprising:
- a first sub-assembly;
- a bolt disposed on the first sub-assembly to receive a force in a radial direction relative to an axis of the bolt;
- and
- a second sub-assembly rotatable relative to the first sub-assembly via the bolt,
- wherein rotation of the second sub-assembly relative to the first sub-assembly is configured to be restricted by a connection between the bolt and at least one of the first sub-assembly and the second sub-assembly,
- wherein the bolt is rotatably mounted in a hole defined by one of the first sub-assembly and the second sub-assembly, an inner circumference of the hole being at least partially toothed, and
- wherein the inner circumference of the hole has, at least in the region of the toothed portion, a greater hardness than an outer circumference of the bolt.
A recliner mechanism for adjusting the inclination of a backrest of a vehicle seat relative to a seat part, the recliner mechanism comprising:
- a first fixing plate configured to be connected to the backrest;
- a second fixing plate configured to be connected to the seat part and having a toothed portion, the first fixing plate being rotatable relative to the second fixing plate;
- a latching pawl rotatably mounted on the first fixing plate and configured to engage the toothed portion of the second fixing plate for locking the first fixing plate relative to the second fixing plate;
- a bolt connected fixedly in terms of rotation to the first fixing plate;
- and
- a locking cam rotatably supported by the bolt for holding the latching pawl in engagement with the toothed portion,
- wherein, when a load applies a predetermined radial force to the locking cam, rotation of the locking cam relative to the first fixing plate is configured to be restricted by a connection between the bolt and the locking cam, and
- wherein the connection is created by plastic deformation of one of the bolt and the locking cam against the other of the bolt and the locking cam.
A vehicle seat comprising:
- a backrest and a seat part;
- a recliner mechanism for adjusting the inclination of the backrest relative to the seat part, the recliner mechanism comprising:
- a first fixing plate connected to the backrest;
- a second fixing plate connected to the seat part;
- a latching pawl rotatably mounted on the first fixing plate and configured to engage the second fixing plate for locking the first fixing plate relative to the second fixing plate;
- a bolt connected fixedly in terms of rotation to the first fixing plate;
- and
- a locking cam rotatably supported by the bolt for holding the latching pawl in engagement with the second fixing plate,
- wherein a connection created using plastic deformation between the bolt and the locking cam reduces the rotatability of the locking cam relative to the bolt when an overload force is applied in a radial direction relative to an axis of rotation of the locking cam.
