Embodiment Construction

[0015] Referring to the accompanying drawings, Figure 1 discloses a seat assembly 10 for use in an automobile. The seat assembly 10 includes a seat cushion 11 and a backrest 12 . Each seat cushion 11 and backrest 12 typically includes a rigid frame structure for supporting a contoured foam cushion enclosed by a trim cover. The seat assembly 10 also includes a jointed recliner assembly 20 that operatively connects the seat cushion 11 and the backrest 12 such that the backrest 12 pivots about a pivot 14 between several rearward support positions. .

[0016] Referring to FIG. 2 , the recliner assembly 20 includes a fixed flange or cylindrical housing 30 having an inner annular surface 32 . A plurality of gear teeth 34 extend radially inwardly from a portion of the annulus 32 . A disc-shaped movable flange or carrier disc 40 is rotatably embedded within the annulus 32 of the cylindrical housing 30 adjacent the gear teeth 34 . The driving pin 42 is fixedly mounted on the carrie...

Abstract

A continuously engaged recliner assembly (20) selectively locks a seat back in one of a plurality of reclined positions about a pivot axis relative to a seat cushion on a vehicle seat. The recliner assembly includes a cylindrical housing (30) having an annular rim of gear teeth (34). A carrier plate (40), having outwardly extending drive pins (42), is rotatably nested within the cylindrical housing (30). An input shaft (50) is rotatably journaled to and extends between the cylindrical housing (30) and the carrier plate (40). Rotation of the shaft (30) causes the first and second gear (60, 62) to move in a hypocycloidal motion around the annular rim of gear teeth (34). A biasing member (58) operatively interconnecting the first (52) and second (55) cams rotatably biases the first and second cams in opposing directions, in turn biasing the first (60) and second (62) gears, respectively, in opposing directions against the cylindrical housing (30), thereby minimizing play within the recliner mechanism.

Description

technical field [0001] The present invention relates to a recliner assembly for pivotally adjusting a backrest relative to a seat cushion of a vehicle seat. Background technique [0002] An automobile includes a seat assembly for supporting a seated passenger in the automobile. The seat assembly typically includes a seat cushion and a backrest pivotally connected to the seat cushion by a reclining mechanism allowing the backrest to be adjusted between several reclining positions relative to the seat cushion. Each seat cushion and backrest typically consists of a rigid frame supporting a cellulose foam pad enclosed by a fabric upholstery cover. [0003] Continuously jointed backrest assemblies are well known in the automotive seating art and are commonly used to pivotally connect the backrest to the seat cushion. Continuously joined recliner assemblies generally include a cylindrical inner disc fixedly secured to the seat cushion, and a cylindrical outer disc fixedly secure...
