Embodiment Construction

[0022] In different drawings, the same components have the same reference numerals. For purposes of clarity, only those components that are helpful to the understanding of the invention are shown and described. In particular, the nature of the laser used in the welding method is not described in detail, the invention being compatible with known double beam lasers. Furthermore, the type of components to be welded to the movable part is not fully detailed either, here the invention is also compatible with ordinary welding.

[0023] figure 2 is a side view of a seat 1 for a motor vehicle. Such a seat comprises a seating part 11 to which a backrest 12 is hingedly connected and may have a headrest 13 on top. The seat is supported by a slide rail 2 having a fixed part 22 attached to the frame C of the vehicle either directly or through a support (not shown) and having the seat supported and capable of sliding relative to the fixed part 22 Part 3 of the activity.

Abstract

A method of laser welding of two members by their respective edges, on a first surface of a slideway section, wherein at least a first one of said members is welded by application of two parallel laser beams from a second surface of the slideway section, with a distance between the beams approximately corresponding to the thickness of the first member, to obtain a laser transmission welding in a single run.

Description

technical field [0001] The present invention relates generally to motor vehicle seats and, more particularly, to welding components together. The invention more particularly relates to welding of planar members along their edges on the movable slide rail portion of a vehicle seat. Background technique [0002] Motor vehicle seats are more and more commonly supported by slide rails having a fixed part attached to the vehicle or seat support and having a movable part which can slide relative to the fixed part. The movable portion supports the seat frame and generally has an inverted "U" shape. The seat frame is attached by an upstanding flange welded to the upper surface of the movable part (the back of the "U" shape). Welding is performed by means of laser welding techniques in which a beam of light is directed at the joint between the parts to be welded. [0003] figure 1 An example of conventional welding of a flange 40 on a "U" shaped movable part 3 is shown very schem...
