Embodiment Construction

[0026] according to figure 1 The locking device for a longitudinal adjustment of a motor vehicle seat has a floor rail 20 forming a latching bar 22 . The latter comprises periodically arranged latch holes 24 ; each latch web 26 is located between two latch holes 24 respectively. The longitudinal adjustment device also includes a seat rail 28 to which a locking unit 30 is connected. The locking unit 30 includes a pin guide 32 . Furthermore, it comprises three locking pins 34 which are identical in construction. They protrude through guide holes in the pin guide 32 . Each of the two outer locking pins 34 rests respectively on each adjacent latch web 26 of the latch bar 22 ; the resting contact is free of play. The central locking pin 34 is inactive; it rests on the latch web 26 . Each locking pin 34 is provided with a spring (not shown) biasing it in the position shown. The spring moves its respective locking pin 34 downward. The locking pin 34 includes a collar 36 formin...

Abstract

The locking unit of a longitudinal adjustment device of a motor vehicle seat comprises a) a latching strip (22), which has periodically arranged detent openings (24) and detent ridges (26) and is associated with a bottom rail (20) of the longitudinal adjustment device, and b) a catch unit (30), which is associated with a seat rail (28) of the longitudinal adjustment device and comprises at least two catch pins (34), which independently of each can be engaged in detent openings (24) and disengaged together, each catch pin having a front region (42) with a front end (44), a tapering region (46) which adjoins the front end (44) and cooperates with the detent ridges (26), and a shaft region (47) having an upper end, said region adjoining the tapering region (46). The tapering region (46) tapers, as seen looking at a profile view, from an upper point B to a lower point A. The catch pins (34) have a pin axis (40). The tapering region (46) is delimited by a line (60) which connects the points A and B and which does not have a rectilinear progression. As seen looking from the pin axis, the line (60) is not located outside of a straight line (48) connecting points A and B, and is located within the straight line (48) over at least one third of the distance AB.

Description

technical field [0001] The invention relates to a locking device for a longitudinal adjustment device of a motor vehicle seat, comprising: a) a latch bar comprising periodically arranged latch holes and latch webs, and configured to a floor rail of the longitudinal adjustment device; and b) a locking unit, which is assigned to the seat rail of the longitudinal adjustment device and comprises at least two locking pins which can be latched independently of each other into the latch holes and unlocked together, and which each have A front region with a front end, a conical region behind the front end and cooperating with the latch web, and a shaft region behind the conical region and having an upper end, wherein the conical region is profiled It tapers from an upper point B to a lower point A, and the locking pin has a pin axis. Background technique [0002] Such a locking device is known from DE 10 242 825 A1. With regard to the prior art, further reference is made to DE 197...
