Abstract
A constant engagement linear recliner assembly is provided for implementation with a seat assembly. The constant engagement linear recliner assembly includes a recliner rod in constant mesh engagement with a gear system. As the gear system is caused to rotate, the recliner rod moves linearly with respect to the linear recliner assembly. The linear motion of the recliner rod translates into pivotable motion of a seat back relative to a seat.
Claims32
A linear recliner assembly, comprising;
- a housing;
- a recliner rod able to reciprocate linearly relative to said housing;
- a first gear assembly supported by said housing and having a counter thrust component;
- a second gear assembly supported by said housing and in constant mesh engagement with said first gear assembly and said recliner rod, said constant mesh engagement enabling linear movement of said recliner rod relative to said housing and causing an axial thrust load on said first gear assembly;
- and
- wherein said counter thrust component balances said axial thrust load on said first gear assembly.

A reclining seat assembly, comprising:
- a seat;
- a seat back pivotally adjustable relative to said seat;
- a linear recliner assembly disposed within said seat, said linear recliner assembly including:
- a housing;
- a first gear assembly rotatably supported within said housing and having a counter thrust component;
- a second gear assembly supported by said housing and in constant mesh engagement with said first gear assembly and said recliner rod, said constant mesh engagement enabling linear movement of said recliner rod relative to said housing and causing an axial thrust load on said first gear assembly;
- a recliner rod connected between said second gear assembly and said seat back;
- and
- wherein said second gear assembly is in constant engagement with said recliner rod for enabling linear movement of said recliner rod relative to said housing, said counter thrust component balances said axial thrust load on said first gear assembly, and linear movement of said recliner rod enables pivotal movement of said seat back relative to said seat.
