Abstract

Seat pan for fastening to a seat frame of a vehicle seat. The seat pan has a profile structure made up of multiple profiles, and on its bottom side has crossbeam receptacles, preferably tube receptacles which are open at the bottom, for placement on a crossbeam, in particular a transverse tube of the seat frame, which extends in the transverse direction. The seat pan is preferably injection-molded from a plastic material, wherein through holes which extend through the profile structure in the vertical direction are formed between the profiles, preferably between all profiles.

Claims

1. Seat pan for fastening to a seat frame of a vehicle seat, the seat pan comprising:

a) a profile structure made up of multiple profiles; and

b) the seat pan having a bottom side, a longitudinal direction, and a transverse direction, and the seat pan on its bottom side having crossbeam receptacles for placement on a crossbeam which extends in the transverse direction.

2. Seat pan according to claim 1, wherein:

a) the seat pan is injection-molded from a plastic material.

3. Seat pan according to claim 1, wherein:

a) through holes are provided which extend through the profile structure in the vertical direction and which are formed between the multiple profiles.

4. Seat pan according to claim 3, wherein:

a) the profile structure is formed solely from the multiple profiles and from through holes which are formed between the multiple profiles.

5. Seat pan according to claim 1, wherein:

a) the crossbeam receptacles are tube receptacles for accommodating a transverse tube of the seat frame which extends in the transverse direction; and

b) the tube receptacles have a configuration that is open at the bottom, preferably open in a jaw-like manner, for fitting onto the transverse tube.

6. Seat pan according to claim 5, wherein:

a) the tube receptacles are configured for snap-locking or clipping attachment to the front transverse tube.

7. Seat pan according to claim 1, wherein:

a) the multiple profiles include a circumferential profile which surrounds the seat pan on three sides and is configured for placement on side profiles of the seat frame; and

b) the circumferential profile is configured as a U profile that is open at the bottom.

8. Seat pan according to claim 7, wherein:

a) the multiple profiles include a rear transverse profile on which front spring connections are provided for accommodating subsuspension springs.

9. Seat pan according to claim 8, wherein:

a) the multiple profiles include longitudinal profiles and transverse profiles, and a lattice structure is made up of the longitudinal profiles and transverse profiles, between which through holes are formed, and the lattice structure is provided between the circumferential profile and the rear transverse profile.

10. Seat pan according to claim 1, wherein:

a) the multiple profiles each are configured as one of the following profiles;

I profile, T profile, Z profile, L profile, U profile, V profile.

11. Seat pan according to claim 1, wherein:

a) the multiple profiles have a widened, flattened top side for accommodating a seat cushion placed thereon.

12. Seat pan according to claim 8, wherein:

a) at least one, in particular multiple, flexible areas are formed between the circumferential profile and the transverse profile to provide deformability of the profile structure via the crossbeam of the seat frame which bends forward, or downward and forward, during a head-on collision.

13. Seat pan according to claim 12, wherein:

a) the at least one flexible area is formed by material weakening, in particular by a lower vertical height of its profiles.

14. Seat pan according to claim 12, wherein:

a) the at least one flexible area is formed by a flexible profile cross section of its profiles, in particular by a V profile or a horizontal I profile.

15. Seat part arrangement for placement on a seat frame of a vehicle seat, wherein the seat part arrangement includes:

a) a seat pan according to claim 1 for fastening to the seat frame of a vehicle seat;

b) a rear subsuspension fastening, and subsuspension springs which extend in the longitudinal direction and which are mounted between the seat pan and the rear subsuspension fastening, and which are spaced apart from one another by cross-connections, in particular spring retainers.

16. Seat part arrangement according to claim 15, wherein:

a) the seat pan and the rear subsuspension fastening are separate from one another, the seat pan being configured for fixed attachment to the seat frame.

17. Seat part arrangement according to claim 15, wherein:

a) the seat pan and the subsuspension fastening are rigidly connected to one another or designed in one piece, preferably in one piece as an injection-molded part made of a plastic material, the seat pan being adjustable, in particular pivotable, with respect to the seat frame.

18. Vehicle seat, including a seat frame, and a seat part arrangement according to claim 15, wherein:

a) the seat pan is placed on a transverse tube of the seat frame, and is preferably secured in a positive-fit manner by a securing device.

19. Vehicle seat according to claim 18, wherein:

a) the subsuspension fastening is placed and snap-locked on a rear transverse tube of the seat frame.

20. Vehicle seat according to claim 18, wherein:

a) the seat pan is height-adjustable or pivotable with respect to the seat frame by a motorized or manual pivoting apparatus.
