US Patent:

48888540, Dec 26, 1989

Filed:

Apr 17, 1989

Appl. No.:

7/339537

Inventors:

Ronald W. Russell - Utica MI
Larry R. Cox - Brownstown MI

Assignee:

Chrysler Motors Corporation - Highland Park MI

International Classification:

E05D 710

US Classification:

16266

Abstract:

A pair of separable hinge assemblies mount a seat cushion on a vehicle for positioning between a normal seating mode and a folded stored mode. The hinge assemblies each comprise a body-half hinge plate mounted to the vehicle body and a seat-half hinge plate mounted to the seat cushion hardened undersurface. The body-half plate has upstanding side webs each formed with open end mirror image slots adapted to releasably capture a pintle pin extending transversely between parallel ear portions of the seat-half hinge plate. Each ear portion includes mirror image first and second cam shoulders adapted to frictionally retain the hinge assemblies in their respective normal or folded modes. Upon pivoting the seat cushion to an intermediate position both sets of cam shoulders of each seat-half hinge plate are spaced from their associated body-half plate camming surfaces allowing the separation of the hinge assemblies and removal of the seat cushion.

Abstract:

A pair of separable hinge assemblies mount a seat cushion on a vehicle for positioning between a rearwardly folded regular seating mode and a forwardly folded stored mode. The hinge assemblies each comprise a body-half hinge plate mounted to the vehicle body and a seat-half hinge plate mounted to the seat cushion hardened undersurface. The body-half plate has upstanding side webs each formed with open end mirror image slots adapted to releasably capture a pintle pin extending transversely between parallel ear portions of the seat-half hinge plate. Each ear portion includes mirror image first and second cam shoulders adapted to frictionally retain the hinge assemblies in their respective seating or folded modes. Upon placement of the seat cusion in an intermediate position both sets of cam shoulders of each seat-half hinge plate are spaced from their associated body-half plate camming surfaces. An improved fail-safe arrangement provides arcuate-shaped guide prongs on the seat-half hinge plate adapted for reception in aligned apertures in the body-half hinge plate with the plates in positive full engagement.
