Embodiment Construction

[0025] figure 1 Firstly, a schematic diagram of the motor vehicle seat 1 is shown. The motor vehicle seat 1 does not necessarily represent only the rear seat, it may be any seat in the vehicle. A motor vehicle seat 1 is equipped with a foldable backrest or back 2 and a seat surface 3 . The back or backrest 2 can be passed along the figure 1 Move in the direction of the arrow to move from an upright position to a folded position.

[0026] When the back 2 is in the upright position, the back 2 is locked relative to the body 5 by the backrest lock 4 . Once the backrest lock 4 is unlocked, the back 2 can be folded down onto the seat surface 3 in a figure 1 The position shown in dashed lines allows access to, for example, a luggage compartment not shown in detail behind the back 2 or substantially at the rear of the motor vehicle. The back 2 is equipped with fixing bolts 6, which are as figure 2 The locking mechanisms 7, 8, 9 of the backrest lock 4 shown cooperate.

Abstract

The object of the invention is a motor vehicle door lock, particularly a backrest lock (4), on a motor vehicle seat (1). The basic construction of the motor vehicle door lock includes a locking mechanism (7, 8, 9) consisting essentially of a rotary latch (9), a ratchet pawl (7) and a blocking element (8) for the ratchet pawl (7). In addition, a drive unit (15, 16, 17) that acts on a triggering element (12) is provided. According to the invention, the drive unit (15, 16, 17) is constructed as a linear adjustment drive (15, 16, 17), which acts on the triggering element (12) so that it interacts in succession, first with the blocking element (8) and then with the ratchet pawl (7).

Description

technical field [0001] The invention relates to a motor vehicle door lock, in particular a backrest lock on a motor vehicle seat, having a locking mechanism consisting essentially of a rotary locking fork, a locking pawl and a locking element for the locking pawl, and acting on the triggering element drive unit. Background technique [0002] In motor vehicle door locks having a locking mechanism essentially comprising a rotary yoke, a pawl / pawl and a locking element, the locking element usually helps to ensure that the locking pawl is supported thereon and is locked. In this case, the locking element is often referred to as the second pawl. The purpose of the locking element or ratchet retaining pawl is generally to enhance the security of the locking in case of accidental opening eg during break-in. In contrast, in other locking mechanisms with two pawls, the main purpose is to allow quiet opening and prevent "opening noise" or suppress opening related noises, or at least...
