Abstract
A seat hinge assembly is provided and includes a support rotatably supporting an arm and further supporting a locking arrangement for locking the arm in either an upright or forward fold position. The locking arrangement includes a lock-pin slidably supported by the support and a cam for selectively interfacing the lock-pin. The locking arrangement further includes a pair of lock plates rotatably supported by the support and in selective engagement with the lock-pin. The lock plates slidably support a stop pin that is concurrently slidable within the support. The lock-pin is engageable with the arm for locking the arm in an upright position and the stop pin is engageable with the arm for locking the arm in a fold position.
Claims28
A seat hinge assembly, comprising:
- a support;
- an arm pivotally supported by said support for rotation relative said support;
- a lock plate pivotally supported by said support;
- a lock pin slidably supported by said support and interfacing said lock plate;
- and
- a lock rivet slidably supported by both said support and said lock plate;
- said lock plate movable between a first position and a second position, said lock plate in said first position positioning said lock pin to selectively block rotation of said arm when said arm is in a first orientation relative to said support and said lock plate in said second position positioning said lock rivet to selectively block rotation of said arm when said arm is in a second orientation relative to said support.
A seat hinge assembly, comprising:
- a support;
- an arm pivotally supported by said support;
- a lock plate pivotally supported by said support;
- a first pin and a second pin slidably supported by said support and interfacing said lock plate, said first pin concurrently engaging said arm and said lock plate to block movement of said arm when said arm is in a first position relative to said support and said first pin engaging said lock plate to bias said second pin into engagement with said arm to block movement of said arm when said arm is in a second position relative to said support.
A seat assembly comprising:
- a seat;
- a seat back;
- a seat hinge supporting said seat and seat back, and further comprising:
- a support disposed within said seat;
- an arm pivotally supported by said support and supporting said seat back for rotation relative said seat;
- a lock plate pivotally supported by said support;
- a first pin and a second pin slidably supported by said support and interfacing said lock plate, said first pin selectively blocking movement of said arm when said arm is in a first position relative to said support and said second pin selectively blocking movement of said arm when said arm is in a second position relative to said support.
