Abstract: An air conditioning device for a vehicle seat, comprising at least one air distribution module (1) having at least one air distribution chamber which is open on the top side (4) opposite the carrier layer (6), and wherein the carrier layer (6) has at least one extension section (12) which projects beyond the part of the carrier layer that is not covered by the bottom side of the insert and can be used for mounting a fan, a fan housing or a fan bracket on the air distribution module (1), by at least surface parts of the extension section (12) surrounding at least partially the fan and/or a fan housing and/or the fan bracket. The extension section (12), or a respective tab (13) as part of the extension section (12), is provided with at least one adhesive layer (18) on its top and/or bottom side.

Abstract: A steering wheel cover, having a circumferential length and a transverse width, comprises a plurality of layers that cover each other at least partially in projection. The layers include a lower electrically conductive shielding layer and an upper cover layer, between which are arranged, starting from the shielding layer, an insulation layer and at least one electrically conductive sensor layer. The shielding layer and/or the sensor layer has/have a conductor structure with conductors extending in the length and width directions of the steering wheel cover. The shielding layer and/or the sensor layer is/are electrically connected to connecting conductors of a connecting cable. The electrical connection is formed by a metal foil. The steering wheel cover serves to detect whether a driver's hand is on the steering wheel.
