AI Technical Summary

Technical Problem

Existing continuously adjustable locking systems for vehicle seats suffer from micro-displacements and loss of support during vehicle accelerations and decelerations, leading to unsatisfactory bracing conditions and alignment issues.

Method used

A continuously adjustable slide locking system with a buttress locking mechanism using a rail, first and second locking members, and clamping elements that ensure bracing in both sliding directions, even during micro-displacements, by utilizing elastic means and a stop means to maintain contact with the rail, allowing for unlimited adjustment positions.

Benefits of technology

The system provides stable locking in an unlimited number of positions, preventing micro-displacements and maintaining alignment, even under stress conditions, thus ensuring reliable seat adjustment.

Abstract

This disclosure relates to a system (1) for locking a continuously adjustable vehicle seat slide, comprising: - the slide (2) comprising a first lower slide element (20) configured to be fixed to a vehicle floor, and a second upper slide element (21) configured to slide along the first slide element; - a locking system by wedging comprising: - a rail (3) extending lengthwise along the slide, fixed relative to the first slide element; - a first locking member (4) and a second locking member (5) mounted integrally with the second slide element (21), in offset positions along a longitudinal axis of the rail (3), the first locking member (4) configured to brace itself against the rail, under the action of two wedging members (OC1, OC2) which wedge themselves into slots (FE1, FE2).
