Abstract
A fold-flat hinge assembly for use with a seat assembly includes an arm pivotably supported by a support member and adapted to support the seat back, as well as a gear fixedly attached to a shaft that is rotatably supported within a first slot of the support member. The shaft also includes a gear fixedly attached thereto and interfacing said arm. A blocking pin slidably supported by the support member between a first position and a second position and mechanically communicating with the shaft blocks rotation of the arm relative to the support member when in a first position. When the blocking pin is moved to a second position by the shaft interacting with the gear teeth of the arm, the arm is in rotate relative to the support member.
Claims21
A seat hinge assembly, comprising:
- a support including a first slot;
- an arm pivotally mounted to said support;
- a sliding pin operable to prevent movement of said arm relative to said support in a locking position;
- and
- a drive shaft operable to rotate from a first position and slide along said first slot to move said sliding pin from said locking position without moving said arm relative said support, and operable in a second position to move said arm relative said support.
A hinge assembly for use with a seat and seat back, said hinge assembly, comprising:
- a support including an elongated slot therein;
- an arm supported by said support and adapted to support the seat back;
- a sliding pin movable between a first position and a second position relative said support, said sliding pin preventing rotation of said arm relative to said support in said first position and allowing said arm to rotate relative to said support in said second position;
- and
- a shaft disposed within said elongated slot of said support and operable to interface said arm as said shaft slides in said elongated slot to move said sliding pin from said first position to said second position before driving said arm to move relative said support.
A seat assembly, comprising:
- a seat;
- a seat back connected to said seat;
- a hinge assembly, including:
- a support including a first slot;
- an arm pivotally mounted to said support;
- a sliding pin operable to prevent movement of said arm relative to said support in a locking position;
- and
- a drive shaft operable to rotate from a first position and slide along said first slot to move said sliding pin from said locking position without moving said arm relative said support, and operable in said second position to move said arm relative said support.
