Device for receiving functional elements
View Patent ↗A device ( 2 ) for accommodating functional elements in regions of a motor vehicle interior that are subjected to mechanical forces at least at times, having a base layer ( 8 ), an intermediate layer ( 10 ) and a cover layer ( 12 ), wherein the layers ( 8, 10, 12 ) are arranged so as to at least partially overlap one another, wherein the intermediate layer ( 10 ) has at least one support element ( 14 ) for the transmission of mechanical loads between the base layer ( 8 ) and cover layer ( 12 ), which element is made, in particular, of a firm but flexible material. In addition to the support element ( 14 ), additional functional elements ( 18 ) are arranged in the remaining space ( 16 ) between the base layer ( 8 ), the cover layer ( 12 ) and the support element ( 14 ).
1. A device for accommodating functional elements in regions of a vehicle interior that are subject to mechanical loads comprising:
a vehicle seat comprising a cushion core for supporting a passenger, and a climate control device, wherein the climate control device comprises an upper air distribution device at a first side of the cushion core facing the passenger to distribute air along the first side of the cushion core, a lower air distribution device at a second side facing away from the passenger to distribute air along the second side of the cushion core, and a connecting device for transferring air between the upper and lower air distribution devices, wherein each air distribution device comprises:
a base layer;
an intermediate layer configured to allow air distribution therethrough;
a cover layer, the layers being arranged so as to at least partially overlap one another, and wherein the intermediate layer comprises at least one support element for the transmission of mechanical loads between the base layer and cover layer and a textile support medium, said at least one support element adhered to said textile support medium and preserving air distribution through said intermediate layer when said mechanical loads are present, said at least one support element comprising a plurality of elongated coils made from a substantially planar band of plastic material, each of the plurality of elongated coils arranged approximately parallel to each other with respect to their longitudinal axes and parallel to the intermediate layer; and
electrical functional elements arranged in a space between the base layer and the cover layer.
2. A device according to claim 1 wherein each of the upper air distribution device, lower air distribution device and connecting device include an elongated hollow space accommodating at least a portion of the intermediate layer and in whose air-conducting cross-section, at least one support element is provided.
3. A device according to claim 2 wherein the connecting device comprises at least one recess in the cushion core connected to the intermediate layer of the upper air distribution device or the intermediate layer of the lower air distribution device so as to permit the passage of air.
4. A device according to claim 3 wherein at least a portion of the intermediate layer is routed around the cushion core at a side thereof, from the first side to the second side, and wherein a conducting device is accommodated in said portion.
5. A device according to claim 1 wherein the functional element is a sensor for detecting pressure or temperature, the sensor being arranged beneath the support element.
6. A device according to claim 1 further comprising at least one heating component comprises a PTC element.
7. A device according to claim 1 wherein the connecting device comprises at least one recess in the cushion core connected to the intermediate layer of the upper air distribution device or the intermediate layer of the lower air distribution device so as to permit the passage of air.
8. A device according to claim 7 comprising at least one heating conductor arranged in at least one intermediate space between at least two support elements in the intermediate layer.
9. A device according to claim 1 wherein at least a portion of the intermediate layer is routed around the cushion core at a side thereof, from the first side to the second side, and wherein a conducting device is accommodated in said portion.
10. A device according to claim 1 wherein the cushion core comprises a plurality of recesses which connect a plurality of individual sections of the intermediate layer arranged on the first side of the cushion core to the intermediate layer arranged on the second side of the cushion core.
11. A device according to claim 10 wherein the plurality of sections are separated from one another and spaced apart.
12. A device according to claim 1 comprising an essentially liquid-impermeable layer arranged on a side of the intermediate layer facing the cushion core.
13. A device according to claim 12 wherein the essentially liquid-impermeable layer comprises the same material as the cushion core.
14. A device according to claim 1 comprising at least one heating conductor arranged in at least one intermediate space between at least two support elements in the intermediate layer.
15. A device according to claim 1 comprising a plurality of elongated intermediate spaces formed by the support elements, and wherein at least one heating conductor is arranged in at least two such intermediate spaces.
16. A device according to claim 1 comprising a plurality of elongated intermediate spaces formed by the support elements, and wherein at least one heating conductor is fixed to the base layer or cover layer at a transition from one intermediate space to the other intermediate space.
17. A device according to claim 16 wherein the at least one heating element is fixed by an adhesive strip arranged substantially perpendicular to the intermediate spaces.
18. A device according to claim 1 wherein said at least one support element maintains a hollow space in said intermediate layer.
