Abstract

An adjustable booster-type seat having a base 10 for supporting the seat on a flat surface, a riser 12 mounted for height adjustment on the base, a body support 14 having a seat and back mounted for arcuate motion on the riser 12 for changing the angular position of the body support 14 and being adjustable in height by virtue of the adjustability of the riser on the base. A restraint bar 16 is detachably connected to the body support and in turn adjustably carries a tray 18 enabling the tray to be moved toward and away form the back and to be mounted at different angles with respect to the body support 14.

Claims

1. A booster seat comprising, a base, a seat, a curved platform defining an arc on the base supporting a complementary curved portion on a surface of the seat to permit relative movement along the arc, at least one slot in the curved platform, and at least one tab carried on the seat extending through a slot and engaging a surface of the platform on an opposite side of the platform from the seat and backrest to guide the seat with respect to the base during relative movement along the arc.

2. The booster seat of claim 1 wherein the tab is formed as a monolithic portion of the seat.

3. The booster seat of claim 1 wherein the at least one slot comprises two slots and the at least one tab comprises two tabs each carried on the seat and each extending through a slot and engaging a surface of the platform on an opposite side of the platform from the seat and backrest to guide the seat with respect to the base during relative movement along the arc.

4. The booster seat of claim 1 wherein the at least one slot comprises three slots and the at least one tab comprises three tabs each carried on the seat and each extending through a slot and engaging a surface of the platform on an opposite side of the platform from the seat and backrest to guide the seat with respect to the base during relative movement along the arc.

5. The booster seat of claim 4 wherein one of the tabs and slots is located generally intermediate the other two tabs and slots.

6. The booster seat of claim 3 comprising two rails on the platform, each rail being adjacent one of the slots.

7. The booster seat of claim 1 wherein the seat is monolithically formed and has hollow armrests.

8. The booster seat of claim 1 wherein the curved platform is monolithically formed and has hollow side portions that fit within hollow armrests on the seat.

9. The booster seat of claim 1 wherein the seat has hollow armrests, the curved platform has hollow side portions that fit within hollow armrests on the seat and the base has side portions adapted to fit within the hollow side portions of the curved platform.

10. The booster seat of claim 1 wherein a latch is coupled to at least one of the curved platform and curved portion on a surface of the seat and a complimentary holding surface is coupled to the other of the curved platform and curved portion on a surface of the seat.

11. The booster seat of claim 10 wherein the latch complimentary holding surface comprise a rack and a tab in complimentary selective engagement whereby the seat and curved platform are locked to arrest arcuate movement and unlocked to permit arcuate movement.

12. The booster seat of claim 1 further comprising a height adjustment means for adjusting the height of the curved platform with respect to the base.

13. The booster seat of claim 1 further comprising a stop on the platform adapted to engage a projection on the bottom of the seat and an abutment at the other end of the platform adapted to engage a tab.

14. The booster seat of claim 1 wherein the platform is monolithic.

15. The booster seat of claim 9 wherein, the seat has a seating surface between the hollow armrests and on the opposite side of the seating surface there is provided guides adapted to contact side portions of the curved platform.

16. The booster seat of claim 1 comprising legs adapted to be removably attached to the base to raise and lower the level of the seat.

17. A booster seat comprising, a base, a seat, means for supporting the seat and backrest with respect to the base to permit relative movement along an arc, means for locking and releasing the seat and backrest with respect to the base in a position from upright to reclined, and means for raising and lowering the seat and backrest on the base.

18. A booster seat comprising, a base, a seat, a riser on the base supporting the seat and adapted to raise and lower the seat, and at least two telescoping members between the base and riser and adapted to limit movement in the telescoping direction.

19. The booster seat of claim 18 wherein the telescoping members have an antirotational fit.

20. The booster seat of claim 19 wherein the antirotational fit comprises fluting.

21. The booster seat of claim 18 wherein the at least two telescoping members comprise three telescoping members.

22. The booster seat of claim 21 wherein the base has antiskid material coupled to the bottom.

23. A booster seat comprising, a base, a seat including a seat with a seating surface between spaced hollow arms, a monolithic riser having a curved platform portion defining an arc and supporting the seat on the base to permit movement of the seat along the arc from an upright position to a reclined position, the curved platform portion being between spaced hollow walls of the riser, arcuate tracks on a surface of the curved platform portion of the riser facing the seat, slots in the riser adjacent the arcuate tracks receiving arms extending from the seat and backrest with at least one tab on each arm, each tab engaging a guide surface of the riser facing away from the seat and backrest, the guide surface being shaped to guide the riser and seat and backrest during relative arcuate movement, at least one stop member on a surface of the riser adjacent the seat and backrest engaging the seat and backrest to arrest arcuate movement in one direction, at least one abutment member on an opposite side of the riser from the seat and backrest engaging a tab to arrest arcuate movement in a second direction, abutment surfaces on the seat and backrest adapted to engage the arcuate tracks for guiding movement of the seat and backrest along the arc, guides supported on the seat on a side opposite the seating surface and facing the riser, the guides adapted to contact the riser, a rack in a recess in the seat and a lever in a recess on the riser, the lever being adapted to selectively engage the rack at intervals along the arc whereby the riser is locked to arrest arcuate movement and unlocked to permit arcuate movement.
