Abstract

A method for adjusting a vehicle seat includes moving each of a set of first valves respectively associated with ones of a group of first bladders into an open position allowing the receipt of air into and fluidic communication among the group of first bladders, inflating the first group of bladders to a predetermined pressure, and closing each of the set of first valves to maintain an inflation level of each of the first bladders.

First claim

What is claimed is:

1. A method for adjusting a vehicle seat, comprising:
upon initially making a determination that the vehicle seat is unoccupied:
simultaneously moving each of a set of first valves respectively associated with ones of a group of first bladders into an open position allowing air to flow into, between, and among the group of first bladders and ;
inflating the first group of bladders to a predetermined collective pressure; and

upon, subsequently, determining that the seat is occupied, simultaneously closing each of the set of first valves to maintain an air distribution among of each of the first bladders at the predetermined collective pressure resulting from the seat becoming occupied before simultaneously closing each of the first valves.

2. The method of claim 1 , wherein the first bladders are located in one of a cushion or a seatback of the vehicle seat.

3. The method of claim 1 , further including receiving a signal from an occupancy sensor in the seat to make the determination that the vehicle seat is unoccupied and the determination that the vehicle seat is occupied.

4. The method of claim 3 , wherein the valves are simultaneously closed after the vehicle seat has subsequently been determined to be occupied for a predetermined time interval to allow air to flow between and among the first bladders according to a distribution of weight of an occupant over the first bladders.

5. The method of claim 4 , wherein closing the valves results in a respective level of inflation of each of the first bladders corresponding to the distribution of weight of the occupant over the first bladders.

6. The method of claim 1 , further including:
upon initially making the determination that the vehicle seat is unoccupied:
simultaneously moving each of a group of second valves respectively associated with ones of a group of second bladders into an open position allowing air to flow into, between, and among the group of second bladders; and

inflating the second group of bladders to the predetermined collective pressure simultaneously with the group of first bladders; and
upon, subsequently, determining that the seat is occupied, closing each of the set of second valves to maintain air distribution among of each of the second bladders at the predetermined collective pressure resulting from the seat becoming occupied before simultaneously closing each of the second valves.

7. The method of claim 6 , wherein:
the first group of bladders are placed in fluidic communication by way of a first manifold coupled between the pump and each of the first group of bladders;
the second group of bladders are placed in fluidic communication by way of a second manifold coupled between the pump and each of the second group of bladders;
before closing each of the set of first valves, the predetermined collective pressure of each of the first bladders is temporarily maintained by a first check valve coupled between the pump and the first manifold; and
before closing each of the set of second valves, the predetermined collective pressure of each of the second bladders is temporarily maintained by a second check valve coupled between the pump and the second manifold.

8. The method of claim 6 , wherein:
inflating the first group of bladders to the predetermined collective pressure and closing each of the set of first valves to maintain the air distribution among of each of the first bladders at the predetermined collective pressure of the first bladders adjusts a profile of a cushion of the vehicle seat; and
inflating the second group of bladders to the predetermined collective pressure and closing each of the set of second valves to maintain the air distribution among of each of the second bladders at the predetermined collective pressure adjusts a profile of a seatback of the vehicle seat.

9. The method of claim 1 , wherein inflating the first group of bladders to a-the predetermined collective pressure is carried out by controlling a pump coupled with each of the first valves.

10. The method of claim 9 , wherein:
the first group of bladders are placed in fluidic communication by way of a first manifold coupled between the pump and each of the first group of bladders; and
before closing each of the set of first valves, the predetermined collective pressure among the first bladders is temporarily maintained by a first check valve coupled between the pump and the first manifold.

11. The method of claim 1 , wherein:
closing each of the set of first valves is carried out only after upon determining that the seat has been occupied for a predetermined time interval, after being initially unoccupied; and
a resulting level of inflation of each of the first bladders after closing each of the set of first valves corresponds to the distribution of weight of the occupant over the first bladders.

12. A method for adjusting a vehicle seat, comprising:
upon initially determining that the seat is unoccupied, moving each of a set of first valves respectively associated with ones of a group of first bladders into an open position with the first bladders in mutual fluidic communication to allow air to flow into, between, and among the first bladders according to a distribution of weight of an occupant over the first bladders when the seat, subsequently, becomes occupied;
inflating the first group of bladders to a predetermined collective pressure; and
upon, subsequently, determining that the seat is occupied, simultaneously closing each of the set of first valves to maintain an air distribution among of each of the first bladders at the predetermined collective pressure resulting from the distribution of weight of the occupant.

13. The method of claim 12 , wherein:
each of the set of first valves are closed only after upon determining that the seat has been occupied for a predetermined time interval, after being initially unoccupied; and
a resulting level of inflation of each of the first bladders after closing each of the set of first valves corresponds to the distribution of weight of the occupant over the first bladders.

14. The method of claim 12 , wherein determining that the seat is unoccupied is carried out by communicating with an occupancy sensor within the seat.

15. The method of claim 12 , wherein inflating the first group of bladders to the predetermined collective pressure is carried out by controlling a pump coupled with each of the first valves.

16. The method of claim 15 , wherein:
the first group of bladders are placed in fluidic communication by way of a first manifold coupled between the pump and each of the first group of bladders; and
before closing each of the set of first valves, the predetermined collective pressure of each of the first bladders is temporarily maintained by a first check valve coupled between the pump and the first manifold.

17. The method of claim 12 , further comprising:
upon initially making the determination that the vehicle seat is unoccupied:
simultaneously moving each of a set of second valves respectively associated with ones of a group of second bladders into an open position allowing the receipt of air into and fluidic communication among the group of second bladders independent of the first bladders; and
inflating the second group of bladders to a second predetermined collective pressure; and

upon, subsequently, determining that the seat is occupied, closing each of the set of second valves to maintain an air distribution among of each of the first bladders at the predetermined collective pressure resulting from the distrib
