Vehicle seat frame

a seat frame and vehicle technology, applied in the field of vehicle seat frames, can solve the problems of frame failure, laborious and expensive frame fabrication and assembly, and the support of foam cushions may not be uniform, so as to reduce the center of gravity of the seat assembly, and the cost of manufacturing

Abstract

A seat frame comprises a unitary magnesium die cast body having a top, a bottom, two sides, and front and back surfaces. The front surface has an outer perimeter flange positioned adjacent the two sides and the top of the body. An inner perimeter flange is spaced from and generally coextensive with the outer perimeter flange. The front surface also has at least one generally horizontally oriented flange and at least two generally diagonally oriented flanges. This arrangement, together with the use of the die cast magnesium, results in a lightweight yet strong and durable frame that provides generally uniform support to the overlying seat cushion. The frame body is also provided with a large aperture that is positioned to desirably lower the seat assembly center of gravity.

Description

BACKGROUNG OF THE INVENTION

[0001] The present invention relates generally to vehicle seating and, more particularly, to an improved vehicle seat frame designed primarily for over the road truck seating.

[0002] Vehicle seating, such as that used in cars and trucks, typically includes an internal frame constructed from metal sheet stock or tubing. A foam cushion, with either a separate or integral upholstered cover, is assembled onto or molded over the frame. Most conventional truck seats are made using a metal tube frame, and frame failure is a common problem. In addition to mechanical failure, the fabrication and assembly of the frame, when constructed from either sheet metal or tubing, can be labor intensive and expensive. Another problem associated with these conventional frame designs is that the support for the foam cushion may not be uniform.

[0003] These problems can be avoided to some extent by using a one piece frame; one, for example, made by injection molding a plastic fr...
