8 . The seat of claim 7 , wherein a pinion gear is engaged with the plurality of teeth on the rack, and a pinion shaft, attached to the pinion gear, is located through the lower slide to a motor located in the motor housing of the lower slide.
9 . The seat of claim 1 , wherein the seat base substrate and flexible main member are unitary, one-piece and integrally formed of a flexible material.
10 . The seat of claim 1 , wherein at least a portion of a front edge portion of the flexible main member has a predisposed downward curl with respect a body portion of the flexible main member.
11 . The seat of claim 1 , wherein the flexible main member has a plurality of hook apertures integrally formed therein, wherein at least one connector strip has at least one hook formed thereon and is adapted for selective location in one of the hook apertures, wherein seat trim is connected to a body portion of the connector strip to connect the seat trim with the flexible main member.
12 . The seat of claim 1 , wherein the flexible main member is adapted to have a first generally planar state, a second general J-shape and a third general C-shape.
13 . The seat of claim 12 , wherein at least one spring metal strip is located in a recess on an upper surface of the flexible main member to assist in holding the third general C-shape.
14 . The seat of claim 1 , wherein the flexible main member is attached to a seat base frame portion, wherein the flexible main member has a width substantially similar to a width of a cushion member attached thereto.
15 . A seat, comprising:
a seat base substrate for suspension and support comprising a flexible main member;
a drive mechanism comprising a lower slide and an upper slide, wherein said upper slide selectively moves with respect to the fixed lower slide via a rack and pinion system;
a pusher releasably attached to the upper slide, wherein the pusher contacts the flexible main member; and
a trim ring attached to the lower slide,
wherein the lower slide comprises:
a motor housing and a first slot wall extending generally parallel a motor housing wall, wherein a gap exists between the motor housing wall and the first slot wall, and
a plurality of slide tabs.
16 . The seat of claim 15 , wherein the upper slide comprises
a slide rail adapted to be at least partially received with the slide tabs;
a plurality of attachment features comprising slots on a front of the upper slide;
a second slot wall adapted to selectively move in the gap between the motor housing wall and the first slot wall;
a step in an upper wall of the upper slide, wherein the step is comprised of a plurality of teeth forming a rack of the rack and pinion system.
17 . The seat of claim 16 , wherein a pinion gear is engaged with the plurality of teeth on the rack, and a pinion shaft, attached to the pinion gear, is located through the lower slide to a motor located in the motor housing of the lower slide.
18 . The seat of claim 15 , wherein a channel extends within at least the flexible main member, wherein the channel has at least one retention feature for seat trim integrally formed therewith.
