Linear recliner with plastic housing
First Claim
1. A linear seat recliner for controllably adjusting the angular position of a seat back relative to a seat base, comprising:
- a driven mechanism including a recliner rod adapted to be coupled to one of the seat back and seat base;
a drive mechanism;
a transmission assembly operably interconnecting said drive mechanism and said driven mechanism, said transmission assembly including a gear retainer assembly and a mounting assembly, said mounting assembly including a second plate nesting within a first plate and securing said gear retainer assembly therebetween, and coupling said gear retainer assembly to the other of the seat back and seat base, said gear retainer assembly including a gear housing formed of a polymeric material.

Abstract
A seat recliner that controllably adjusts the angular position of a seat back relative to a seat base structure and is responsive to remote actuation by an operator. The recliner includes a driven mechanism adapted to be connected to the seat back, a drive mechanism rotatable in a first and second direction, and a transmission assembly operably interconnecting the drive mechanism and the driven mechanism. The transmission assembly includes a gear retainer assembly and a mounting assembly. The mounting assembly is adapted to be connected to one of the seat base and seat back. The gear retainer assembly includes a gear housing formed of a polymeric material and adapted to accommodate the drive and driven mechanisms for operative interconnection, whereby rotation of a transmission rod in the first or second direction causes a recliner rod to move relative to the housing in a corresponding first and second linear direction.
