Motor vehicle accessory such as an armrest
The invention relates to a motor-vehicle accessory, comprising a first part and at least one second part pivotal about an axis (a) relative to the first part in at least one bearing assembly ( 20 a, 20 b ), and the bearing assembly ( 20 a, 20 b ) comprises a bearing pin ( 14 ) on which a bearing sleeve ( 22 ) is coaxial to the bearing axis (a), and the bearing pin ( 14 ) forms a head ( 19 ) with an axial retaining face ( 30 ). The particularity is that of the bearing pin ( 14 ) having first coupling formation that engages in a second coupling formation of the bearing sleeve ( 22 ) and prevents relative rotation in a pivot direction (u 1 , u 2 ) between the bearing sleeve ( 22 ) and the bearing pin ( 14 ).
1. A motor-vehicle accessory comprising;
a first part;
at least one second part; and
a bearing assembly supporting the first part in the second part for pivoting of the second part about an axis relative to the first part, the bearing assembly comprising a bearing pin on which a bearing sleeve is coaxial to the bearing axis, the bearing pin having a first coupling formation that engages in a second coupling formation of the bearing sleeve and prevents relative movement in a pivot direction between the bearing sleeve and the bearing pin.
2. The motor-vehicle accessory according to claim 1 , wherein the first coupling formation is formed on an outer surface of the bearing pin, and the second coupling formation is formed on an inner surface of the bearing sleeve, the inner surface being in contact with the outer surface.
3. The motor-vehicle accessory according to claim 1 , wherein the coupling formations are formed by teeth or polygonal supports.
4. The motor-vehicle accessory according to claim 1 , wherein the bearing pin passes through a hole in a holding strut of a vehicle frame and engages in the arm.
5. The motor-vehicle accessory according to claim 1 , wherein the bearing sleeve forms a flange with an axial counterface.
6. The motor-vehicle accessory according to claim 5 , further comprising:
at least one functional element between the retaining face and the counterface.
7. The motor-vehicle accessory according to claim 6 , wherein the functional element is a disk spring.
8. The motor-vehicle accessory according to claim 1 , wherein the bearing pin is fixed to the first part or to the second part.
9. The motor-vehicle accessory according to claim 1 , wherein the bearing assembly has a washer in contact with a vehicle frame in order to absorb and distribute forces acting on the vehicle frame.
10. An armrest for a vehicle wherein the armrest is a motor-vehicle accessory according to claim 1 , a vehicle frame forming the first part and a pivotal arm forming the second part.
