Drive mechanism for a seat cushion length extender
A drive mechanism for a seat cushion length extender may have a lower slide, an upper slide slidably engaged with the lower slide, a linkage member having a threaded rod having a flange end with an aperture therethrough and a pin located through the linkage flange aperture and the linkage member aperture.
1 . A drive mechanism for a seat cushion length extender, comprising:
a lower slide having two lateral side portions bounding a central portion, wherein an area of the central portion is recessed below the lateral side portions, and another portion of the central portion comprises a motor aperture,
an upper slide having rails slidably engaged with the lateral side portions and at least one linkage flange with an aperture extending from a lower surface of the upper slide,
a linkage member comprising a threaded rod having a flange end with an aperture therethrough; and
a pin located through the linkage flange aperture and the linkage member aperture;
wherein receptacles adapted to receive portions of a pusher are located at laterally outboard portions along a forward portion of the upper slide.
2 . The drive mechanism of claim 1 , wherein the lower slide, the upper slide and the threaded rod each have longitudinal axis that are parallel to one another.
3 . The drive mechanism of claim 1 , wherein the lateral side portions of the lower slide define slide channels.
4 . The drive mechanism of claim 2 , wherein the recessed area of the central portion is longitudinally aligned with the longitudinal axis of the threaded rod.
5 . The drive mechanism of claim 4 , wherein the central portion has a motor mount with a depression therein for the threaded rod, wherein two transmission fastener apertures are located on either side of the depression.
6 . The drive mechanism of claim 5 , wherein the motor mount at least partially bounds the motor aperture.
7 . The drive mechanism of claim 5 , wherein one portion of a motor extends into the motor mount.
8 . The drive mechanism of claim 1 , wherein the rails of the upper slide are located laterally outboard of a central portion of the upper slide.
9 . The drive mechanism of claim 1 , wherein the recessed area of the lower slide is sized and shaped to selectively receive the linkage flange of the upper slide.
10 . The drive mechanism of claim 1 , wherein a pinion aperture is located through the lower slide in a forward central portion of the lower slide.
11 . The drive mechanism of claim 5 , wherein the transmission fasteners extend into the motor mount parallel to the threaded rod.
12 . The drive mechanism of claim 1 , wherein the pin extends transverse to the threaded rod.
13 . The drive mechanism of claim 1 , wherein the threaded rod extends parallel to the rails.
14 . The drive mechanism of claim 1 , wherein each of the upper and lower slides are one-piece, unitary and integrally formed.
15 . A drive mechanism for a seat cushion length extender, comprising:
a lower slide having two lateral side portions bounding a central portion, wherein the central portion comprises a motor aperture,
an upper slide having rails slidably engaged with the lateral side portions,
a linkage member comprising a threaded rod,
wherein the central portion has a motor mount with a depression therein for the threaded rod, wherein two transmission fastener apertures are located on either side of the depression.
16 . The drive mechanism of claim 15 , wherein the motor aperture extends through the lower slide from an upper surface of the lower slide to a lower surface of the lower slide.
17 . The drive mechanism of claim 15 , further comprising a pin, wherein the upper slide has at least one linkage flange with an aperture extending from a lower surface of the upper slide, wherein the threaded rod has a flange end with an aperture therethrough, and wherein the pin is located through the linkage flange aperture and the linkage member aperture.
18 . A drive mechanism for a seat cushion length extender, comprising:
a lower slide having two lateral side portions bounding a central portion,
an upper slide having rails slidably engaged with the lateral side portions,
a linkage member comprising a threaded rod having a flange end with an aperture therethrough;
wherein receptacles for receiving portions of a pusher are located at laterally outboard portions along a forward portion of the upper slide.
19 . The drive mechanism of claim 18 , wherein the central portion comprises a motor aperture and wherein the upper slide has at least one linkage flange with an aperture extending from a lower surface of the upper slide.
20 . The drive mechanism of claim 19 , further comprising a pin located through the linkage flange aperture and the linkage member aperture.
