Abstract
Trim covers with reinforcing assemblies for providing straight seams and smooth/symmetrical trim surfaces along one or more seams. For example, the trim covers may employ one or more wires arranged along or proximate the one or more seams such that the seams are straight and not wavy. In one or more embodiments, the trim cover may also employ one or more elastic members to provide tension to the surface such that it does not wrinkle and/or sag.
Claims20
A trim cover, comprising:
- a trim material comprising an outer surface configured to contact an occupant, an inner surface opposite the outer surface configured to contact a cushion assembly defining an occupant support surface, and the trim material defining a seam positioned to extend over a gap defined by the cushion assembly;
- a flap comprising a first end and a second end opposite to the first end, wherein the flap is attached to the inner surface of the trim material at the first end;
- a rigid member positioned at the second end of the flap proximate to the seam, providing stress on the trim material when arranged on a seat assembly;
- an elastic member comprising a primary end and a secondary end, such that the elastic member is coupled with the second end of the flap and the rigid member at the primary end;
- and
- a retainer coupled to the rigid member via the elastic member at the secondary end of the elastic member and secured to a seat frame,
- wherein the trim material has a first position and a second position, and the rigid member, coupled with the elastic member and the retainer, is configured to reinforce the seam by tensioning the trim material in the first position and the second position.
4 more elements
A seat assembly, comprising:
- a frame;
- a cushion assembly supported by the frame and defining a gap;
- and
- a trim cover disposed over the cushion assembly and defining a seam disposed proximate the gap, the trim cover comprising:
- a flap comprising a first end and a second end opposite to the first end, wherein the flap is attached to the trim cover at the first end;
- a rigid member positioned at the second end of the flap extending along the seam such that tension is applied to support the seam when the trim cover is in a first position and a second position;
- an elastic member comprising a primary end and a secondary end, such that the elastic member is coupled with the second end of the flap and the rigid member at the primary end;
- and
- a retainer coupled to the rigid member via the elastic member at the secondary end of the elastic member and coupled to the frame, wherein the rigid member, coupled with the elastic member and the retainer, is configured to reinforce the seam by tensioning the trim cover in the first position and the second position.
6 more elements
A trim assembly, comprising:
- a trim defining a seam, the trim comprising an outer surface to contact an occupant and an inner surface to contact a cushion assembly defining a gap to facilitate movement from a first position to a second position, trim cover being positioned such that it bridges the gap when covering the cushion assembly and the seam is disposed along the gap;
- a flap comprising a first end and a second end opposite to the first end, wherein the flap is attached to the inner surface of the trim at the first end;
- a rigid member positioned at the second end of the flap proximate to the seam to provide stress on the trim when arranged on a seat assembly;
- an elastic member comprising a primary end and a secondary end, such that the elastic member is coupled with the second end of the flap and the rigid member at the primary end;
- and
- a plurality of retainers coupled to the rigid member via the elastic member at the secondary end of the elastic member and secured to a seat frame,
- wherein the rigid member, coupled with the elastic member and the plurality of retainer, is configured to reinforce the seam by providing tension along the seam.
