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;

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

c) 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; and

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

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

4. Seat pan according to claim 1, wherein:

a) the crossbeam receptacles have a configuration that is open at the bottom for fitting onto the crossbeam.

5. Seat pan according to claim 4, wherein:

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

6. 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.

7. Seat pan according to claim 1, 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 a circumferential profile and the rear transverse profile.

8. 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.

9. Seat pan according to claim 1, wherein:

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

10. Seat pan according to claim 1, wherein:

a) at least one flexible area is formed between a circumferential profile and the rear 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.

11. Seat pan according to claim 10, wherein:

a) the at least one flexible area is formed by a lower vertical height of its profiles.

12. Seat pan according to claim 10, wherein:

a) the at least one flexible area is formed by a V profile or a horizontal I profile cross section.

13. Seat part arrangement for placement on a seat frame of a vehicle seat, the seat part arrangement comprising:

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

b) the seat pan including;

i) a profile structure made up of multiple profiles;

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

iii) 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; and

c) 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 spring retainers.

14. Seat part arrangement according to claim 13, 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.

15. Seat part arrangement according to claim 13, wherein:

a) the seat pan and the rear subsuspension fastening are connected to one another, and the seat pan is adjustable with respect to the seat frame.

16. Vehicle seat according to claim 13, wherein:

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

17. 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;

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;

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

d) the circumferential profile being configured as a U profile that is open at the bottom;

e) the multiple profiles including a rear transverse profile on which front spring connections are provided for accommodating subsuspension springs; and

f) the multiple profiles including 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.

18. 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;

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;

c) the multiple profiles including a rear transverse profile on which front spring connections are provided for accommodating subsuspension springs;

d) at least one flexible area being formed between a circumferential profile and the rear 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; and

e) the at least one flexible area being formed by a lower vertical height of its profiles.
