Abstract

The invention relates to a seat part for a vehicle seat, in particular a motor vehicle seat, having a seat pan (1) made of sheet metal, a seat cushion applied to the seat pan (1) and a cable assembly (17) running in the seat cushion.

In order to make possible simple and economical installation of the cable assembly and manufacture of the seat part, the invention provides that the seat pan (1) is formed as a deep-drawn part and channels (8, 11, 12) are formed in the seat part (1), in which the cable assembly (17) is accommodated.

Claims

1. A seat part for a vehicle seat, in particular for motor vehicle seats, having a seat pan (1) made of sheet metal, a seat cushion arranged on the seat pan (1) and a cable assembly (17) running in the seat cushion, characterized in that the seat pan (1) is formed as a deep-drawn part, and channels (8, 11, 12) are formed in the seat pan (1), in which the cable assembly (17) is accommodated.

2. The seat part according to claim 1, wherein the channels (8, 11, 12) are formed on the top (6) of the seat pan (1).

3. The seat part according to claim 1, wherein the channels (8, 11, 12) have a rectangular or trapezoidal cross-section.

4. The seat part according to claim 1, wherein the channels (8, 11, 12) transition into each other.

5. The seat part according to claim 1, wherein the seat pan (1) is formed in a single deep-draw process with a middle zone (2), side walls (3), a rear zone (4) and the channels (8, 11, 12).

6. The seat part according to claim 1, wherein the seat pan (1) has at least one longitudinal channel (8) extending up to a front zone (5) and a transverse channel (11) extending transversely over the seat pan (1).

7. The seat part according to claim 6, wherein the longitudinal channel (8) continues at its front end into a flattening (10) extending over a front zone (5) of the seat pan (1).

8. The seat part according to claim 6, wherein in the seat pan (1) at least one, for example two rear longitudinal channels (12) extending from the transverse channel (11) rearwards are formed, whose rear ends continue into a raised rear zone (4) of the seat pan (1).

9. The seat part according to claim 1, wherein the cable assembly (17) has power and/or control lines for one or several of the following function groups:

seat depth adjustment, occupancy sensor mat, heating pad, pyrotechnics, seat inclination adjustment forward, seat inclination adjustment rearwards, anti-submarining bar, headrest inclination adjustment, lumbar adjustment, side air bag, seat length adjustment.

10. A method for manufacturing a seat part comprising at least the following steps:

Deep-drawing of the seat pan (1) from a sheet metal matrix while at the same time forming the channels (8, 11, 12) in one deep-drawing stroke,

inserting a prefabricated cable assembly (17),

application of the seat cushion on the seat pan.
