Abstract

A vehicle seat includes a group of first inflatable bladders, each first bladder having a respective first valve coupled therewith and a pump coupled with each of the first valves. The seat further includes a controller in communication with the pump and with the first valves to cause the pump to inflate the first group of bladders to a predetermined pressure and to close the valves to maintain a subsequent inflation level of each of the first bladders.

Claims

1. A vehicle seat, comprising:

a group of first inflatable bladders, each first bladder having a respective first electromechanical valve coupled therewith;

a pump coupled with each of the first valves;

an occupancy sensor; and

a controller electrically connected with the pump, the occupancy sensor, and with each of the first valves and, upon initially receiving a first signal from the occupancy sensor indicating that the seat is unoccupied, opening all of the first valves to allow air to flow between and among the first bladders and causing the pump to simultaneously inflate the group of first bladders to a predetermined collective pressure and, upon subsequently receiving a second signal from the occupancy sensor indicating that the seat occupied, simultaneously closing all of the first valves to maintain an air distribution level of each of the first bladders according to a distribution of weight of an occupant over the first bladders resulting from the seat being occupied before the controller simultaneously closes all of the first valves.

2. The vehicle seat of claim 1, further comprising:

a first manifold coupled between the pump and each of the first group of bladders; and

a first check valve coupled between the pump and the first manifold.

3. The vehicle seat of claim 1, further comprising a group of second inflatable bladders, each second bladder having a respective second electromechanical valve coupled therewith, wherein:

the pump is further coupled with each of the second valves; and

the controller is further coupled with the second valves such that, upon the pump inflating the first bladders, the second bladders are also simultaneously inflated to the predetermined collective pressure and the controller closes all of the second valves to maintain the resulting inflation level of each of the second bladders.

4. The vehicle seat of claim 3, further comprising:

a first manifold coupled between the pump and each of the first inflatable bladders;

a second manifold coupled between the pump and each of the second inflatable bladders;

a first check valve coupled between the pump and the first manifold; and

a second check valve coupled between the pump and the second manifold.

5. The vehicle seat of claim 3, further comprising:

a cushion and a seatback coupled with the cushion, wherein;

the first bladders are positioned within the cushion; and

the second bladders are positioned within the seatback.

6. The vehicle seat of claim 1, wherein the controller, upon receiving the second signal from the occupancy sensor indicating that the seat a, occupied, delays for a predetermined time interval before simultaneously closing all of the first valves such that a resulting level of inflation of each of the first bladders corresponds to a distribution of weight of an occupant over the first bladders.

7. A vehicle seat, comprising:

a group of first inflatable bladders, each first bladder having a respective first electromechanical valve coupled therewith;

a first manifold coupled with each of the first bladders and providing fluidic communication among the group of first bladders when the first valves are all in respective open positions;

a pump coupled with the first manifold;

a first check valve coupled between the pump and the first manifold;

an occupancy sensor; and

a controller electrically connected with the occupancy sensor, the pump, and with each of the first electromechanical valves and, upon initially receiving a first signal from the occupancy sensor indicating that the seat is unoccupied, opening all of the first valves to allow air to flow between and among the first bladders and causing the pump to simultaneously inflate the first group of bladders to a predetermined collective pressure and, upon subsequently receiving a second signal from the occupancy sensor indicating that the seat occupied, to simultaneously close all of the first valves to maintain an air distribution level of each of the first bladders according to a distribution of weight of an occupant over the first bladders resulting from the seat being occupied before the controller simultaneously closes all of the first valves.

8. The vehicle seat of claim 7, further including a cushion and a seatback rotatably coupled with the cushion, wherein:

the group of first inflatable bladders is positioned within one of the seatback or the cushion.

9. The vehicle seat of claim 7, further comprising:

a group of second inflatable bladders, each second bladder having a respective second electromechanical valve coupled therewith;

a second manifold coupled with each of the second inflatable bladders and providing fluidic communication among the second bladders when the second valves are all in respective open positions, the second manifold being further coupled with the pump; and

a second check valve coupled between the pump and the second manifold.

10. The vehicle seat of claim 7, further comprising:

a cushion and a seatback coupled with the cushion, wherein;

the first bladders are positioned within the cushion; and

the second bladders are positioned within the seatback.

11. The vehicle seat of claim 7, wherein the controller, upon detecting that the seat has been occupied, delays for a predetermined time interval before simultaneously closing all of the first valves such that the resulting level of inflation of each of the first bladders corresponds to a distribution of weight of an occupant over the first bladders.
