Abstract

A vehicle seat assembly includes a back rest and a seat cushion that may be reconfigurable to alternatively form a forward facing adult seating surface and child seat mounting surface. The back rest may be provided in a substantially horizontal orientation to offer an extended lower leg support surface for a child's lower legs and feet while seated in a rear facing child seat. The vehicle seat assembly may include a support mechanism to interconnect the seat cushion to a vehicle, enabling selective longitudinal repositioning of the vehicle seat assembly with respect to fixed adjacent interior vehicle structure to establish a variable longitudinal clearance there-between. A rear facing child seat forming back rest and seat cushion portions may be carried by the child seat mounting surface of the vehicle seat assembly. The back rest may be removable from the vehicle seat assembly.

First claim

What is claimed is:

1. A vehicle seat assembly, comprising:
a seat cushion, the seat cushion forming an upwardly facing surface configured to alternatively provide part of an adult seating surface and a child seat mounting surface; and
a back rest forming a front surface, wherein the back rest is selectively:
(i) repositionable between a first orientation in which the front surface provides a forward facing part of the adult seating surface to form a forward facing adult seat, and a second, substantially horizontal orientation in which the front surface provides an upwardly facing extended leg support surface substantially continuously with an upper surface of a primary leg support surface formed by a rear facing child seat carried by the upwardly facing surface of the seat cushion; and
(ii) removable from the vehicle seat assembly.

2. The vehicle seat assembly of claim 1 , further comprising a support mechanism configured to interconnect the seat cushion to a host vehicle, and enable selective longitudinal repositioning of the vehicle seat assembly with respect to a fixed adjacent interior vehicle structure to establish a variable longitudinal clearance there-between.

3. The vehicle seat assembly of claim 2 , wherein the vehicle seat assembly is longitudinally spaced from an opposed forward edge surface of the interior vehicle structure by a clearance volume having a vertical height, a lateral width, and a longitudinal depth.

4. The vehicle seat assembly of claim 3 , wherein the vertical height, the lateral width, and the longitudinal depth are constant for a given fixed longitudinal positioning of the vehicle seat assembly with respect to the interior vehicle structure.

5. The vehicle seat assembly of claim 3 , wherein the vertical height extends from a floor panel of the host vehicle to the upper surface of the primary leg support surface formed by the rear facing child seat.

6. The vehicle seat assembly of claim 1 , further comprising a pivotal hinge mechanism configured to releasably interconnect the back rest with the seat cushion.

7. The vehicle seat assembly of claim 6 , wherein the pivotal hinge mechanism provides an attachment point for the rear facing child seat.

8. The vehicle seat assembly of claim 1 , wherein the primary leg support surface has at least one touch point, and the seat cushion forms a rearwardly facing bolster forming a rearwardly facing extended leg support surface when the back rest is removed from the vehicle seat assembly with at least one touch point in a same substantially vertical plane as the primary leg support surface's at least one touch point.

9. The vehicle seat assembly of claim 1 , wherein the vehicle seat assembly is a single passenger vehicle seat assembly.

10. A vehicle seat assembly, comprising:
a seat cushion, the seat cushion forming an upwardly facing surface configured to alternatively provide a child seat mounting surface and part of an adult seating surface, and a rearwardly facing bolster forming a rearwardly facing extended leg support surface with at least one touch point;
a back rest forming a front surface, the back rest removed from the vehicle seat assembly, and selectively interconnectable with the seat cushion in a position in which the front surface provides a forward facing part of the adult seating surface to form a forward facing adult seat; and
a rear facing child seat carried by the child seat mounting surface, the rear facing child seat forming a rearwardly facing primary leg support surface with at least one touch point in a same substantially vertical plane as the extended leg support surface's at least one touch point, whereby the primary leg support surface's at least one touch point and the extended leg support surface's at least one touch point support a child's lower legs and feet substantially vertically while seated in the rear facing child seat.

11. The vehicle seat assembly of claim 10 , wherein the rearwardly facing bolster is longitudinally spaced from an opposed forward edge surface of a fixed adjacent interior vehicle structure by a sufficient dimension, with the back rest removed from the vehicle seat assembly, to provide longitudinal clearance and the extended leg support surface.

12. The vehicle seat assembly of claim 10 , further comprising a pivotal hinge mechanism configured to releasably interconnect the back rest with the seat cushion.

13. The vehicle seat assembly of claim 12 , wherein the pivotal hinge mechanism provides an attachment point for the rear facing child seat.

14. The vehicle seat assembly of claim 10 , further comprising a support mechanism configured to interconnect the seat cushion to a host vehicle, and enable selective longitudinal repositioning of the vehicle seat assembly with respect to a fixed adjacent interior vehicle structure to establish a variable longitudinal clearance there-between.

15. A second row vehicle seat assembly, comprising:
a seat cushion forming an upwardly facing surface configured to alternatively provide a child seat mounting surface and part of an adult seating surface;
a rear facing child seat carried by the upwardly facing surface of the seat cushion, the rear facing child seat forming a primary leg support surface with at least one touch point; and
a back rest forming a front surface, the back rest in a substantially horizontally oriented position in which the front surface provides an upwardly facing extended leg support surface with at least one touch point in a same substantially horizontal plane as the primary leg support surface's at least one touch point, and selectively repositionable between the substantially horizontally oriented position and an alternative position in which the front surface provides a forward facing part of the adult seating surface to form a forward facing adult seat.

16. The second row vehicle seat assembly of claim 15 , wherein the back rest is selectively removable from the second row vehicle seat assembly, and the seat cushion forms a rearwardly facing bolster longitudinally spaced from an opposed forward edge surface of a fixed adjacent interior vehicle structure by a sufficient dimension, when the back rest is removed from the second row vehicle seat assembly, to provide longitudinal clearance and a rearwardly facing second extended leg support surface with at least one touch point, with the second extended leg support surface's at least one touch point in a same substantially vertical plane as a second at least one touch point on the primary leg support surface.

17. The second row vehicle seat assembly of claim 15 , further comprising a support mechanism configured to interconnect the seat cushion to a host vehicle, and enable selective longitudinal repositioning of the second row vehicle seat assembly with respect to a fixed adjacent interior vehicle structure to establish a variable longitudinal clearance there-between.
