Automotive seat rail guide has transverse shaft linked to longitudinal upper rails by strengthened interface

摘要

An automotive seat has a frame with a transverse shaft (5) coupled to longitudinal upper rails (3, 4). A supplementary stiffening member is located between the upper rails and the transverse shaft. The stiffening member is formed by e.g. a seam, twisting, solder, welding, bonding, flange or beading.
