A slide rail for a vehicle seat

Abstract

The invention relates to a slide rail for a vehicle seat, comprising a slide case, a slide core and steel balls, the lower end of the inner vertical folded wall of the slide core is connected with the lower end of the outer vertical folded wall through an arc-shaped folded wall; the upper and lower ends of the slide shell are respectively There are upper groove-shaped folding wall and lower groove-shaped folding wall; the arc-shaped folding wall of the sliding core and the lower groove-shaped folding wall at the lower end of the sliding case form a lower steel ball channel; steel balls are arranged in the lower steel ball channel; The upper end of the vertical folding wall is an inner bending wall, and the inner bending wall and the upper groove-shaped folding wall at the upper end of the slide case form an upper steel ball channel, and steel balls are arranged in the upper steel ball channel. The invention has the advantage that when the vehicle swings and bumps to give traction force and impact force to the slide rail, the sliding core and the sliding shell can be perfectly combined and move smoothly.

[0002] At present, the slide rail used for vehicle seats includes a sliding case, a sliding core and a steel ball. The lower end of the inner vertical folding wall of the sliding core is connected with the lower end of the outer vertical folding wall through an arc-shaped folding wall; The folded wall and the lower groove-shaped folded wall; the arc-shaped folded wall of the sliding core and the lower groove-shaped folded wall at the lower end of the slide case form a steel ball channel; steel balls are arranged in the steel ball channel; the slide rail used for the vehicle seat swings when the car is running , The traction and impact force of the slide rail given by the bumps, especially when the seat belt fixed point is placed on the rear side of the slide rail, the slide rail works under the state of half rolling friction and half sliding friction, which may easily cause the adjustment of the slide rail to be stuck.
