Embodiment Construction

[0036] In all figures, the same reference numerals are given to the same elements. For greater clarity, only those elements necessary for an understanding of the invention have been shown.

[0037] if available at figure 1 and 2 As seen in , a lock 1 for opening a motor vehicle component such as a door comprises a housing 2 (for example of plastic material) and a back plate 3 (for example of metal) which defines a holding compartment 4 by while closing case 2 (see image 3 and 4 partial sectional view). The back panel 3 is intended to be fixed to a motor vehicle door. The holding compartment 4 is intended to house, inter alia, the rotary locking bolt 5 and the pivoting pawl 6 .

[0038] Furthermore, the lock 1 may comprise a metal plate 9 partially covering the housing 3, which is in contact with the back plate 3, so that the housing 2 is not subjected to deformation stresses when the lock on the door is locked.

[0039] The locking bolt 5 can be rotated about the axis ...

Abstract

The invention relates to a rotary locking bolt for a motor vehicle door lock, intended to collaborate with a striker of said motor vehicle, said rotary locking bolt (5) comprising a metal body (14) and having a cylindrical through-opening (12) intended to collaborate with a corresponding guiding surface (13) of said lock (1) so as to pivot about an axis of rotation (I) between a position in which the lock (1) is open and a position in which the latter is closed, in which it collaborates with the striker, characterized in that said metal body (14) has compensating projections (16a-16f) projecting around said cylindrical through-opening (12) on each side of the ends of the cylindrical through-opening (12). The invention also relates to a motor vehicle door lock (1) provided with such a rotary locking bolt (5).

Description

technical field [0001] The invention relates to a rotary locking bolt for a motor vehicle lock, in particular for a motor vehicle door lock. The invention also relates to said door lock. Background technique [0002] A typical lock includes a housing, a plate and a metal back plate that define a retaining compartment for accommodating retaining elements such as rotary locking bolts and pivoting pawls. The back plate allows the housing to be closed and the lock to be secured to the frame of the motor vehicle. The locking bolt is intended to cooperate with a striker secured to the edge of the door. The pawl cooperates with the locking bolt to catch it and hold it in a position corresponding to the closed position of the lock. [0003] A motor vehicle manufacturer may require the design and production of a range of door locks with the same specifications, particularly for the point for securing to the vehicle body and / or for the "S point" (where the lock is in the closed pos...
