Abstract

A vehicle includes a frame, a passenger presence sensor mounted thereto, and a seat assembly removably connected to. The seat assembly includes a driver seat disposed on the frame and a passenger seat disposed on the frame rearward of the 5 driver seat, at least the passenger seat being selectively disposed on the frame. A rigid passenger presence responsive member (PPRM) is retained in the passenger seat and movable with respect to the frame between at least a first position and a second position responsive to a weight of a passenger seated on the passenger seat. The PPRM is coupled to the passenger presence sensor in at least one of the first and 10 second positions, the passenger presence sensor is thereby configured to detect a presence of the passenger. Removable passenger seats for a vehicle are also disclosed.

First claim

What is claimed is:

1. A vehicle comprising:
a frame;
a passenger presence sensor mounted to the frame;
a seat assembly being removably connected to the frame and comprising:
a driver seat disposed on the frame;
a passenger seat disposed on the frame rearward of the driver seat, at least the passenger seat being selectively disposed on the frame; and
a rigid passenger presence responsive member (PPRM) being etained irn the passenger seat and movable with respect to the frame between at least a first position and a second. position responsive to a weight of a passenger seated on the passenger seat,
the PPRM being coupled to the passenger presence sensor in at least one of the first and second positions, the passenger presence sensor being thereby configured to detect a presence of the passenger.

2. The vehicle of claim 1 , wherein the PPRM is coupled to the passenger position sensor the first position and the second position.

3. The vehicle of claim wherein the passenger sensor is disposed on the frame below the passenger seat.

4. The vehicle of claim 1 , wherein the vehicle further comprises a control unit communicatively coupled to the passenger presence sensor and configured to receive a signal therefrom indicative of a position of the PPRM, the control unit being configured to control an operation of the vehicle based on the signal.

5. The vehicle of claim 1 , wherein the passenger seat comprises:
a passenger seat base being rigid and removably connected to the frame;
a passenger seat cushion connected to the passenger seat base and disposed thereabove when the passenger seat is disposed on the frame, the passenger seat cushion being resiliently mpressible responsive to the weight of the passenger seated thereon; and
the PPRM, the PPRM being movable responsive to the compression of the passenger seat cushion.

6. The vehicle of claim 5 wherein the passenger seat cushion comprises:
an upper surface;
a lower surface disposed opposite the upper surface and facing the seat base; and
a recess extending from the lower surface towards the upper surface, the PPRM being disposed at least partly in the recess.

7. The vehicle of claim 5 , wherein the passenger seat base comprises a passenger seat base opening extending therethrough, the passenger seat base opening being aligned with the passenger presence sensor and the PPRM, at least a portion of at least one of the PPRM and the passenger presence sensor being disposed in the passenger seat base opening.

8. The vehicle of claim 7 , wherein the passenger seat cushion comprises:
an upper surface;
a lower surface opposite the upper surface and facing the seat base; and
a recess extending from the lower surface towards the upper surface, the recess being aligned with the seat base opening, the PPRM being disposed at least partly in the recess.

9. The vehicle of claim 7 , wherein a portion of the PPRM extends through the passenger seat base opening.

10. The vehicle of claim 9 , wherein the seat base further comprises:
at least one projection extending into the opening to prevent the PPRM from moving out of the passenger seat through the passenger seat base opening, the PPRM being thereby retained in the passenger seat.

11. the vehicle of claim 10 , wherein the projection engages the PPRM to prevent rotation the PPRM.

12. The vehicle of claim 11 , wherein the projection is T-shaped and the PPRM comprises a T-shaped slot complementary to the projection, the projection being received in the slot to thereby engage the PPRM.

13. The vehicle of claim 12 , wherein the PPRM is a cylindrical member.

14. The vehicle of claim 13 , wherein the passenger presence sensor is a Hall effect sensor.

15. The vehicl of claim 14 , wherein the Hall effect sensor is disposed on the frame below the passenger seat, a portion of the Hall effect sensor being in contact with the PPRM in the first and second positions and being moveable with the PPRM with respect to the frame,
the PPRM being disposed in the first position responsive to a first force on the PPRM,
the PPRM being disposed in the second position responsive to a second force on the PPRM,
the Hall effect sensor thereby detecting one of the first and second positions of the PPRM and thereby detecting a corresponding one of the first and second forces on the PPRM.

16. The vehicle of claim 15 , wherein the PPRM is disposed in the first position in an absence of the passenger seated on the passenger seat.

17. The vehicle of claim 16 , wherein when the passenger is seated on the passenger seat, the PPRM is disposed in the second position.

18. The vehicle of claim 17 , wherein:
the second position comprising a plurality of passenger present positions, each of the plurality of passenger present positions being indicative of a corresponding passenger weight of a plurality of passenger weights,
the Hall effect sensor thereby detecting the corresponding one of the plurality of passenger weights.

19. The vehicle of claim 15 , wherein:
the PPRM is disposed. in the first position responsive to a first passenger weight of a plurality of passenger weights; and
the PPRM is disposed in the second position responsive to a second passenger weight of the plurality of passenger weights,
the Hall effect sensor thereby being configured to detect one of the first passenger weight and second passenger weight of the plurality of passenger weights.

20. The vehicle of claim 15 , wherein the PPRM is movable to a third position responsive to a third force on the PPRM, the third position being indicative of an inoperative condition of the passenger seat.
