Slide rail for half-step lateral locking of vehicle seat

Abstract

The invention provides a slide rail for half-step lateral locking of a vehicle seat. The slide rail comprises a group of an upper sliding groove and a lower sliding groove, a first linkage piece and a handlebar, wherein the upper sliding groove and the lower sliding groove can be slide relatively; a plurality of limit holes are arranged one side wall of the lower sliding groove; a first group of stop pins arranged in parallel is penetrated in the upper sliding groove; each stop pin is sleeved with a reset spring to lock one limit hole when the stop pin is reset; one end of the linkage piece passes through the upper end face of the upper sliding groove to be hinged with a torsion spring; the torsion spring is fixed on the upper sliding groove; and the handlebar is used for pulling the first linkage piece so as to drive the stop pin to laterally sway to separate from the limit hole through the other end of the linkage piece. According to the invention, the structure characteristics of parts are made good use of to reduce parts and assembly processes and promote the manufacturability in machining and assembly; assembly requirements on common vehicle seats are met; and a plurality of stop pins and limit holes of the lower sliding groove are adopted to perform differential matching in the sliding direction and obtain smaller adjusting steps, thereby improving the reliability and stability of the locking adjustment.

Description

【Technical field】 [0001] The invention relates to a slideway for adjusting the position of a vehicle seat, in particular to a small-step lateral locking slideway for a vehicle seat. 【Background technique】 [0002] In order to meet the needs of different drivers and passengers, most of the current car seats are designed with functions such as manual or automatic adjustment of the front and rear distances, left and right distances, and the inclination angle of the backrest. Among them, the front-back distance adjustment of the seat is frequently used, and the convenience and safety of the adjustment are considered in the design, and the structural requirements for the seat slideway are relatively high. [0003] Generally, the slideway must ensure two functions of position adjustment and positioning after adjustment by an inner concave part sliding relative to an outer convex part. For non-automatic slides, the positioning operation is usually done by a locking member provided...

Problems solved by technology

However, the unlocking method of this utility model is to unlock and lock the locking parts by moving up and down. Such a method will result in insufficient peeling strength of the slide rail up and down, making it difficult to adjust the sliding of the seat.
