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 with a backrest, a riser, means for supporting the seat with respect to the base to permit relative movement along an arc, means for locking and releasing the seat with respect to the base in a position from upright to reclined, and means for raising and lowering the seat on the base, the base including a first side wall and an opposite second side wall, the means for raising and lowering the seat on the base includes a first height adjustment mechanism having a post configured to engage the first side wall of the base and a second height adjustment mechanism having a post configured to engage the second side wall of the base.

2. The booster seat of claim 1, wherein the means for supporting the seat includes a riser having a curved surface, the riser being disposed between the base and the seat, the seat having a surface complementary to the curved surface of the riser.

3. The booster seat of claim 1, wherein the means for supporting the seat includes a riser disposed between the base and the seat, the riser including an arcuate platform with an arcuate track, the seat continuously engaging the track as the seat moves along an arc.

4. The booster seat of claim 1, further comprising:

a riser, wherein the means for locking and releasing the seat includes a latch mechanism coupled to the riser, the latch mechanism being selectively engageable with the seat.

5. The booster seat of claim 4, wherein the seat includes a plurality of openings, and the latch mechanism is selectively engageable with the openings.

6. The booster seat of claim 5, wherein the latch mechanism includes a tab, and the tab is biased into engagement with one of the openings.

7. The booster seat of claim 1, wherein the riser has a first side and an opposite second side, the first height adjustment mechanism being proximate to the first riser side and the second height adjustment mechanism being proximate to the second riser side.

8. The booster seat of claim 7, wherein each base side wall includes a plurality of slots, and each height adjustment mechanism includes a handle, each post of each height adjustment mechanism being selectively engageable with a slot on a base side wall.

9. A booster seat comprising, a base, a seat including a seat with a backrest and 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 with at least one tab on each arm, each tab engaging a guide surface of the riser facing away from the seat, the guide surface being shaped to guide the riser and seat during relative arcuate movement, at least one stop member on a surface of the riser adjacent the seat engaging the seat to arrest arcuate movement in one direction, at least one abutment member on an opposite side of the riser from the seat engaging a tab to arrest arcuate movement in a second direction, abutment surfaces on the seat adapted to engage the arcuate tracks for guiding movement of the seat 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.

10. A booster seat comprising:

a base, the base including opposite side walls with openings formed therein;

a riser, the riser being configured to receive a portion of the base, the riser including an upper surface with an arcuate configuration, a first height adjustment mechanism including a post that is configured to engage an opening in one of the base side walls, and a second height adjustment mechanism including a post that is configured to engage an opening in the other of the base side walls, each of the first and second height adjustment mechanisms being adjustable to raise and lower the riser on the base; and

a seat with a backrest, the seat being mounted on the riser and including a lower surface having an arcuate configuration, the lower surface being substantially complimentary to the upper surface of the riser, the riser and the seat including a latch mechanism being operable to lock and release the seat with respect to the riser.

11. The booster seat of claim 10, wherein the latch mechanism includes a tab moveably mounted on the riser and a plurality of openings provided on the seat, the tab being biased toward the plurality of openings and engageable therewith to lock the seat relative to the riser and prevent movement between the seat and the riser.

12. The booster seat of claim 10, wherein the seat is mounted on the riser so that the seat moves relative to the riser and base along an arc.

13. The booster seat of claim 10, further comprising:

means for limiting the movement of the seat relative to the riser.

14. The booster seat of claim 10, wherein the riser includes cavities configured to receive respective side walls of the base, each of the height adjustment mechanisms being associated with one of the riser cavities.
