Abstract

A method and apparatus of facilitating ingress or egress of a seat having bolsters includes detecting a potential ingress or egress of an occupant to the seat. Upon detection a configuration of the seat is altered from a first position to a second position, wherein a substantially flat surface is formed by a top of a seat portion of the seat and an associated bolster attached to the seat portion.

Claims

1. An active vehicle bolster system, comprising:

a seat;

at least one bolster disposed on one side of the seat;

a detector;

a drive motor coupled to the at least one bolster and the detector, the drive motor operable, upon receiving a first signal from the detector, to cause the at least one bolster to alter position from a first position to a second position, the second position being a position in which a surface of the seat and a surface of the at least one bolster are in a substantially same first plane, the first position being a position in which the surface of the at least one bolster forms a non-zero angle with the first plane,

wherein the seat includes a mat,

wherein the at least one bolster includes a first bolster having a first bolster insert at a first side of the seat, and a second bolster having a second bolster insert at a second side of the seat opposite the first side,

a first cable interlaced through first openings formed through the first bolster insert and first openings formed through the mat;

a second cable interlaced through second openings formed through the second bolster insert and second openings formed through the mat; and

a shaft coupled to the at least one bolster insert and driveable by the drive motor such that in the first position the first and second cables have a level of slack and such that in the second position the first and second cables are pulled tight,

wherein the first openings in the first bolster insert are aligned with one another at an edge of the first bolster insert that is closest to the mat,

wherein the first openings in the mat are aligned with one another at an edge of the mat that is closest to the first bolster insert,

wherein the second openings in the second bolster insert are aligned with one another at an edge of the second bolster insert that is closest to the mat, and

wherein the second openings in the mat are aligned with one another at an edge of the mat that is closest to the second bolster insert.

2. The system of claim 1, wherein the detector sends the first signal to the drive motor upon detecting a potential ingress to or egress from the vehicle.

3. The system of claim 2, wherein the detector receives a transmission from a key fob from the vehicle indicating a potential ingress.

4. The system of claim 2, wherein the detector receives a transmission from the vehicle indicating the vehicle has been placed in park or a parking brake of the vehicle has been set.

5. The system of claim 1, wherein the detector is coupled to a timer that sends a signal to the detector that a predefined amount of time has elapsed, and the detector sends a second signal to the drive motor to cause the at least one bolster to proceed from the second position to the first position.

6. The system of claim 1, wherein the at least one bolster is associated with a seat cushion of the seat.

7. The system of claim 1, wherein the at least one bolster is associated with a back portion of the seat.

14. The system of claim 1, wherein the shaft is coupled to an end of the at least one bolster insert.

8. A system comprising:

a seat;

at least one bolster disposed on one side of the seat;

a detector; and

a drive motor coupled to a first portion of the seat and the detector, the drive motor operable, upon receiving a first signal from the detector, to cause the first portion to alter position from a first position to a second position,

wherein the seat includes a mat,

wherein the at least one bolster includes a first bolster having a first bolster insert at a first side of the seat, and a second bolster having a second bolster insert at a second side of the seat opposite the first side,

a first cable interlaced through first openings formed through the first bolster insert and first openings formed through the mat;

a second cable interlaced through second openings formed through the second bolster insert and second openings formed through the mat; and

a shaft coupled to the at least one bolster insert and driveable by the drive motor such that in the first position the first and second cables have a level of slack and such that in the second position the first and second cables are pulled tight,

wherein the first openings in the first bolster insert are aligned with one another at an edge of the first bolster insert that is closest to the mat,

wherein the first openings in the mat are aligned with one another at an edge of the mat that is closest to the first bolster insert,

wherein the second openings in the second bolster insert are aligned with one another at an edge of the second bolster insert that is closest to the mat, and

wherein the second openings in the mat are aligned with one another at an edge of the mat that is closest to the second bolster insert.

9. The system of claim 8, wherein the first portion is seat cushion portion of the seat.

10. The system of claim 8, wherein the first portion is a back portion of the seat.

11. The system of claim 8, further comprising a timer in communication with the detector, wherein the timer sends a signal to the detector that a predefined amount of time has elapsed, and the detector sends a second signal to the drive motor to cause the first portion to proceed from the second position to the first position.

12. The system of claim 8, wherein the second position is a position in which a surface of the seat and a surface of the at least one bolster are in a substantially same first plane, and wherein the first position is a position in which the surface of the at least one bolster is in the first plane and the surface of the seat is in a second plane different from the first plane.

13. The system of claim 12, further comprising:

at least one shaft coupled to the drive motor and the first portion, the at least one shaft being driveable by the drive motor to cause the first portion to move between the first and second positions.
