Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) In the drawings:

(2) FIG. 1 is a schematic side view of a vehicle comprising a vehicle seat;

(3) FIG. 2 is a schematic perspective view of a vehicle seat;

(4) FIG. 3 is a schematic sectional view of a vehicle seat; and

(5) FIG. 4 is a schematic sectional view of a detail of a vehicle seat.

DESCRIPTION OF PREFERRED EMBODIMENTS

(6) Referring to the drawings, FIG. 1 shows a schematic side view of a vehicle 1 comprising a vehicle seat 2. The vehicle 1 comprises an open chassis.

(7) The vehicle seat 2 comprises a seat cushion 3 and a backrest 4.

(8) Because of the open chassis it is possible that water intrudes into a passenger area and the vehicle seat 2 may get wet.

(9) FIG. 2 shows a schematic perspective view of a vehicle seat 2, for example the vehicle seat 2 shown in FIG. 1. FIG. 3 shows a schematic sectional view of the vehicle seat 2 and FIG. 4 shows a schematic sectional view of a detail of a vehicle seat 2 within the range of the seat cushion 3.

(10) The vehicle seat 2 comprises the seat cushion 3 and the backrest 4, wherein the backrest 4 comprises a backrest cushion 5.

(11) Furthermore the vehicle seat 2 comprises a cavity 6 located under the seat cushion 3 and under the backrest 4.

(12) The cavity 6 comprises at least one air intake 7, 8, in the shown embodiment two air intakes 7, 8, at least one air outlet 9 and at least one drain port 10, 11, 12, in the shown embodiment three drain ports 10, 11, 12. The at least one air intake 7, 8 is coupled with a heating, ventilation and air conditioning 19.

(13) The cavity 6 is defined between an underside of the seat cushion 3, an underside of the backrest 4 and a drip pan 13 arranged below the seat cushion 3 and the backrest 4. The at least one air intake 7, 8, air outlet 9 and drain port 10, 11, 12 are integrated in the drip pan 13. In the shown embodiment the air intakes 7, 8 are arranged on a front side of the drip pan 13 and the air outlet 9 is arranged on a back side of the drip pan 13. The drain ports 10, 11, 12 are arranged on an underside of the drip pan 13. To avoid a contact between the seat cushion 3 and water in the cavity 6 the seat cushion 3 is kept away from the drip pan 13, e.g. by a suspension 18.

(14) Furthermore, the seat cushion 3 comprises at least one drain channel 14 directed from an upside 3.2 to the underside 3.1. Additionally, the seat cushion comprises at least one air channel 15 connected with the cavity 6.

(15) Moreover, the backrest cushion 5 comprises at least one drain channel 16 directed from a backrest area to the cavity 6 and at least one air channel 17 connected with the cavity 6.

(16) When the vehicle seat 2 gets wet, for example from rain, the water is drained through the drain channels 14, 16 in the drip pan 13 and gets out through the drain ports 10, 11, 12.

(17) To dry the wet seat cushion 3 and the wet backrest cushion 5 the cavity is charged with an air flow F from the heating, ventilation and air conditioning 19. The air flow F flows through the air channels 15, 17, collects the remaining moisture and takes it away through the air outlet 9. To prevent the cavity from intrusion of moist air, the air outlet 9 is designed as a one-way vent in a possible embodiment.

(18) While specific embodiments of the invention have been shown and described in detail to illustrate the application of the principles of the invention, it will be understood that the invention may be embodied otherwise without departing from such principles.
