AI Technical Summary

Technical Problem

Existing motor vehicle seat headrests with a significant gap between vertically extending tubular metal rods provide inadequate protection against whiplash injuries due to excessive head movement and structural deformation during impacts.

Method used

The headrest design features tubular metal rods with a reduced gap between their upper parts, connected by a folded connecting part, allowing the molded plastic structure to slide on these rods, thereby limiting deformation and enhancing safety while freeing up space for additional features like sound transmission modules or lateral support elements.

Benefits of technology

The reduced gap between the rods enhances safety by minimizing head movement and deformation, while also accommodating additional functional elements without increasing the headrest's thickness.

Abstract

The invention relates to a headrest (1) for a motor vehicle seat comprising a frame (2) including two rods (3) symmetrical to each other, a structure (4) slidably mounted on said rods, each of said rods comprising a straight lower portion (5) connected to a straight upper portion (6) by a folded connecting portion (7), the lower portions (5) of said rods being parallel and separated from each other by a first gap (8) and the upper portions (6) of said rods being parallel and separated from each other by a second gap (9) of lesser amplitude than said first gap, said upper portions being housed within said structure, said structure being slidably mounted on said upper portions.
