Abstract

A vehicle seat construction is provided. The preferred embodiment construction includes a seat frame having a curvilinear shaped a seat cushion bun is mounted on top of the frame a seat covering is provided for enclosing the seat cushion bun. The seat cover has along an edge connective means, a flexible non-molded polymeric trim retainer is attached with the frame at at least two separate locations. The trim retainer shapes the cover and is joined to the cover. The trim retainer also retains the cover to the seat cushion bun.

Claims

1. A vehicle seat construction, said construction in combination comprising:

a seat frame having curvilinear shape and including a general U-shaped tubular supporting portion;

a seat cushion bun mounted on said on said tubular portion

a seat cover for enclosing said seat cushion bun, said cover along a lower edge having a connective means; and

a flexible non-molded polymeric trim retainer having a generally flat planar portion which is extending along a vertical plane with means of attachmeht at at least two separate locations with said frame and said tubular supporting portion whereby said trim retainer shapes said cover, and at a lower end of said retainer planar portion, said retainer has means of joining with said cover connective means for retaining said cover to said seat cushion bun thereby retaining said seat cushion bun to said frame.

2. A vehicle seat construction, said construction in combination comprising:

a metallic tubular seat frame having a curvilinear U-shaped tubular supporting portion with two lateral sections projecting forward and joining with a front section;

a foam polymer seat cushion bun having a grooved section aligned with said tubular supporting section and mated therewith and mounted on top of said frame;

a seat cover for enclosing said seat cushion bun having along a lower edge J-shaped connector open towards said foam bun; and

a flexible extruded polymeric trim retainer having a generally flat planar portion which is extending along a vertical plane attached with plastic fasteners with said metal frame at at least two separate points whereby said trim retainer shapes said cover and said trim retainer has an arrow head at a lower end of said retainer planar portion for joining with said cover J-shaped connector for retaining said cover in a tension fit to said seat cushion bun and thereby retaining said seat cushion bun to said frame and wherein said trim retainer holds said cover in a position to exclude said plastic fasteners from view.
