Abstract

A release mechanism for a reclining vehicle seat assembly includes an activation mechanism, for example a lever or handle, and a transmission. The transmission is coupled to the activation mechanism via a wire for releasing a seat back of the vehicle seat assembly. The transmission includes a plurality of meshed gears for transmitting a torque created by movement of the activation mechanism from a gear of the plurality of gears attached to the wire to a shaft associated with the seat back. Rotation of the shaft releases the seat back for rotation. A shield partially covers a side of the base and seat back, and covers the transmission and wire. The activation mechanism is uncovered allowing the passenger to activate the release mechanism and is positioned in a readily accessible zone relative a passenger hip point. The position avoids interference with the seat belt and occupies minimal space between the side shield and vehicle side.

First claim

What is claimed:

1. A reclining vehicle seat assembly, comprising:
a base supported by the vehicle;
a seat back connected to said base for rotation about a shaft;
a transmission including a plurality of gears for rotating said shaft and releasing said seat back;
a side shield attached to said base and covering at least a portion of a side of said base and a side of said seat back; and
a lever attached to the base and said transmission via a wire, wherein said transmission and said wire are covered by said side shield;
wherein (a) at least a portion of said shaft includes a plurality of teeth, and said plurality of gears includes a first gear having internal teeth for meshing with said plurality of teeth, and a second gear attached to said wire such that movement of said lever moves said wire thereby rotating said second gear about a pin extending from a housing and supporting said second gear, (b) said second gear includes first and second arms extending from a hub, said first arm attached to said wire and said second arm forming an arc having a plurality of teeth on an inner side of said arc, and (c) said reclining vehicle seat assembly further includes third and fourth gears for transmitting torque created by movement of said lever from said second gear to said first gear and said shaft, wherein the third and fourth gears each have a plurality of teeth, and said plurality of teeth of said third gear mesh with said plurality of teeth of said second gear and said plurality of teeth of said fourth gear, and said plurality of teeth of said fourth gear further mesh with said plurality of teeth of said first gear.

2. A vehicle incorporating the reclining vehicle seat assembly of claim 1 .

3. The reclining vehicle seat assembly of claim 1 , wherein said plurality of gears are meshed for transmitting torque created by movement of said lever from a gear of said plurality of gears attached to said wire to said shaft.
