Knee retainer with a heat-conducting device

A knee retainer 5 for a vehicle, wherein the knee retainer comprises at least one dissipating device 3 for dissipating tempered air, and wherein the at least one dissipating device 3 is configured to dissipate air which is tempered by an electronic element of the vehicle and is conducted on to the knee retainer 5, in such a manner that the hot air is conducted past a region of the vehicle which is to be protected against temperature effects caused by the tempered air. The at least one dissipating device may be a heat-conducting plate, and the retainer may be arranged such that the dissipating device diverts air past the region such that at least one temperature sensor in the protected region correctly detects the temperature of the vehicle independently of the tempered air. Also provided is an entertainment system configured to conduct air to the dissipating device (s), and a vehicle comprising the knee retainer and entertainment system.
