Vehicle access seating
A vehicle seating system including a mounting assembly; a first slide assembly configured to move linearly relative to an adapter plate; a first drive motor mounted to an under-plate of the first slide assembly, the first drive motor being configured to selectively move the first slide assembly in a liner motion parallel to a longitudinal axis of the adapter plate; a swivel assembly configured to swivel relative to the first slide assembly, wherein the swivel assembly includes an over-plate mounted to a swivel post that rotatably engages the first slide assembly; a second slide assembly configured to move linearly relative to the over-plate; and a second drive motor engaging a seat pan of the second slide assembly and being configured to move the second slide assembly in a liner motion parallel to a longitudinal axis of the seat pan.
1. A method for using a seating system to transition a seat of a vehicle from a drive position to an intermediate pivoted position where the seat is aligned with a vehicle doorway and to an access position with the seat positioned at least partially through the vehicle doorway, comprising:
providing a seat defining a pivotable seat axis and an adapter plate defining an adapter plate static axis wherein the seat axis and adapter plate static axis are substantially parallel to one another when the seating system is in the drive position and wherein the seat axis and adapter plate static axis are not parallel to one another when the seating system is in the intermediate pivoted position and the access position;
in a first sliding step, before the seat is fully pivoted to the intermediate pivoted position, sliding the seat along the seat axis whereby the seat moves linearly relative to a pivot axis of the seat;
pivoting the seat during or after the sliding step to the intermediate pivoted position;
in a second sliding step, extending the seat at least partially out of the vehicle doorway after pivoting the seat by sliding the seat linearly along the pivoted seat axis.
2. The method of claim 1 , further wherein the first sliding step and the pivoting step are activated concurrently to position the seat within a preselected tolerance to a pillar or a longitudinal axis of the vehicle.
3. The method of claim 2 , further wherein sensors define the seat's position relative to the pillar.
4. The method of claim 2 , further wherein sensors defined the seat's position relative to the longitudinal axis.
5. The method of claim 1 wherein the first sliding step includes sliding the seat generally parallel to the adapter plate static axis and along the seat axis for initiating rotation.
6. The method of claim 1 wherein the first sliding step includes sliding the seat away from a dashboard of the vehicle.
7. The method of claim 6 , prior to the first sliding step, the method further comprises the step of sliding the adapter plate along the static adapter plate static axis.
8. The method of claim 1 wherein the first sliding step includes sliding the seat in a direction that reduces a clearance between the seat and a B-pillar of the vehicle.
9. The method of claim 1 wherein the first sliding step includes sliding the seat in a direction that reduces a clearance between the seat and a transmission tunnel.
10. The method of claim 1 further comprising the step of sliding the adapter plate along the static adapter plate static axis during the first sliding step.
11. The method of claim 10 wherein the first sliding step and sliding the adapter plate step are coordinated to adjust an occupant's knee room.
12. The method of claim 10 wherein the first sliding step and sliding the adapter plate step are coordinated to increase an occupant's knee room.
13. The method of claim 10 wherein the first sliding step and sliding the adapter plate step are coordinated to maximize an occupant's knee room.
14. The method of claim 10 wherein the first sliding step includes sliding the seat away from a dashboard of the vehicle.
15. A method for using a seating system to transition a seat of a vehicle from a drive position to an intermediate pivoted position where the seat is aligned with a vehicle doorway and to an access position with the seat positioned at least partially through the vehicle doorway, comprising:
providing a seat defining a pivotable seat axis and an adapter plate defining an adapter plate static axis wherein the seat axis and adapter plate static axis are substantially parallel to one another when the seating system is in the drive position and wherein the seat axis and adapter plate static axis are not parallel to one another when the seating system is in the intermediate pivoted position and the access position;
in a first sliding step, before the seat is fully pivoted to the intermediate pivoted position, sliding the seat whereby the seat moves linearly relative along at least one of the seat axis and the adapter plate static axis;
pivoting the seat during the first sliding step to the intermediate pivoted position;
in a second sliding step, extending the seat at least partially out of the vehicle doorway after pivoting the seat by sliding the seat linearly along the pivoted seat axis.
16. The method of claim 15 wherein the first sliding step includes the seat moving linearly along the seat axis whereby the whereby the seat moves linearly relative to a pivot axis of the seat.
17. The method of claim 15 wherein the first sliding step includes sliding the seat away from a dashboard of the vehicle.
18. The method of claim 15 wherein the first sliding step includes sliding the seat in at least one of a direction that reduces a clearance between the seat and a B-pillar of the vehicle and a direction that reduces a clearance between the seat and a transmission tunnel.
