Seatback lift mechanism for a supine motor vehicle seating assembly
First Claim
1. A vehicle seating assembly comprising:
- a headrest;
a seatback including a central portion and first and second lateral edges, the seatback being operable between an upright position and a reclined position;
an upper back support including a tubular member operably coupled between a bushing and a ratchet latch, the upper back support being adjustably securable in a plurality of positions by the ratchet latch; and
a ratchet drive bracket, wherein the tubular member is coupled to the ratchet drive bracket, the ratchet drive bracket is coupled to a drive gear of the ratchet latch, and movement of the tubular member between a stowed position and a fully deployed position causes the ratchet drive bracket to move the ratchet drive gear relative to a stationary gear.

Abstract
A motor vehicle comprises an upper back support comprising a substantially U-shaped tubular member pivotally attached at a first end to one of a pair of opposed lateral seatback frame members and pivotally attached at a second end to the other of the pair of opposed lateral seatback frame members, a substantially rigid planar base attached to a central portion of the tubular member, a latch operably coupling the first end of the tubular member to the one of a pair of opposed lateral seatback members to restrain the tubular member in one of a plurality of positions between a stowed position and a fully raised position, and a cushion disposed above the upper back support to form a movable exposed surface.

12. A seatback comprising:
-
first and second frame members; an upper back support, wherein the upper back support comprises a tubular member and a supporting member and wherein the upper back support is located between the first and second frame members and is pivotably coupled to the first and second frame members; a drive bracket, wherein the tubular member is coupled to the drive bracket and wherein the drive bracket is pivotably coupled to a ratchet pin that is coupled to the first frame member; a ratchet mounting bracket, wherein the ratchet mounting bracket secures a ratchet latch to the first frame member, the ratchet mounting bracket is coupled to the first frame member with the ratchet pin and a second attachment, a deployment force exerted on the tubular member causes the drive bracket and a drive gear to rotate about the drive pin relative to a stationary gear and the drive gear and the stationary gear are selectively engageable to place the tubular member in one of a plurality of predetermined positions. - View Dependent Claims (13, 14, 15)
