Abstract

The invention relates to an automobile seat sliding rail, in particular to a sliding rail capable of enhancing rigidity modulus. The sliding rail is composed of an upper rail assembly, a lower rail assembly and retainers; the upper rail assembly is slidably arranged in a sliding groove of the lower rail assembly through a pair of retainers, and first protruding ribs and / or steel ball clamping grooves are arranged on the surfaces, in contact with the upper rail assembly and the lower rail assembly, of the retainers at intervals. Steel balls are installed in the steel ball clamping grooves, supporting structures extending backwards in the field length direction of the retainers are arranged at the rear ends of the retainers; and when the upper rail assembly slides backwards to the farthest stroke, the supporting structure provides longitudinal auxiliary supporting for the middle rear section of the upper rail assembly, and the supporting structure makes contact with the lower rail assembly, and a gap is reserved between the supporting structure and the upper rail assembly. The whole upper rail can be supported through the supporting structures, and the mode of the sliding rail can beeffectively improved especially under the working condition of jolting and vibrating, so that the overall rigidity of the sliding rail is improved, and noise generated by the sliding rail in an automobile can be reduced.

Description

technical field

[0001] The invention relates to the improvement of automobile slide rail components, in particular to a slide rail with enhanced rigidity modulus. Background technique

[0002] In order to meet the requirements of passenger comfort, car seats usually need to implement angle adjustment and displacement adjustment, and recliners are generally used for adjustment; displacement adjustment is realized by setting the seat on the slide rail, and there is a liner between the seat and the slide rail Balls are used to reduce friction, and the balls are all set in the cage to prevent scattering.

[0003] Such as Figure 1-3 Shown is the sliding state diagram of the existing car seat slide rail assembly: the movement mode of the cage is rolling; the operation mode of the slide rail is sliding, and the movement stroke of the cage is half of the movement stroke of the slide rail. At this time, because the distance between the rear end of the upper rail and the rear end of...
