The heating device includes an electrically driven heat source and a reflector configured to reflect heat radiation emitted by the heat source in the direction of a passenger compartment of the vehicle. The vehicle further includes a contact protection device which is permeable to radiation so that heat radiation reflected by the reflector or emitted by the heat source radiates into the passenger compartment. The heat source and the reflector are arranged on one side of the contact protection device, and the side is averted from the passenger compartment. ## Claims ### Claim 1 A vehicle, comprising: a heating device having: an electrically operated heat source and a reflector configured to reflect thermal radiation output by the heat source in a direction of a passenger compartment of the vehicle; a contact-protection device, wherein the contact-protection device is permeable to radiation so that the thermal radiation output by the heat source, or reflected by the reflector, is emitted into the passenger compartment, wherein the heat source and the reflector are arranged on a side of the contact-protection device, and the side is averted from the passenger compartment; and a rearward reflector arranged between the heating device and the contact-protection device, wherein the rearward reflector has a rear side that faces the heating device. ### Claim 2 (depends on 1) The vehicle according to claim 1, wherein the heat source is a high-temperature heat source and has a temperature of more than 100° C. ### Claim 3 (depends on 1) The vehicle according to claim 1, wherein the rearward reflector has a rearward reflector layer. ### Claim 4 (depends on 1) The vehicle according to claim 1, wherein the reflector of the heating device extends toward the contact-protection device. ### Claim 5 (depends on 1) The vehicle according to claim 1, further comprising: a thermal insulation layer arranged on a side of the reflector, wherein the side is averted from the contact-protection device. ### Claim 6 (depends on 1) The vehicle according to claim 1, wherein the heat source is designed in the form of a point, a sphere, a line, or a cylinder. ### Claim 7 (depends on 1) The vehicle according to claim 1, wherein a cross section of the reflector is of elliptical design. ### Claim 8 (depends on 1) The vehicle according to claim 1, wherein a cross section of the reflector is of parabolic design. ### Claim 9 (depends on 1) The vehicle according to claim 1, wherein the heat source is arranged at a focal point or on an axis running through a focal point of the reflector. ### Claim 10 (depends on 7) The vehicle according to claim 7, wherein the reflector is arranged such that one of the two focal points lies in the region of a partition wall of the contact-protection device. ### Claim 11 (depends on 7) The vehicle according to claim 7, wherein the reflector is arranged such that the two focal points lie on a side of the contact-protection device, wherein the side is averted from the passenger compartment. ### Claim 12 (depends on 1) The vehicle according to claim 1, further comprising: a ventilation device, said ventilation device configured to blow air into the passenger compartment from a side of the contact-protection device, wherein the side is averted from the passenger compartment. ### Claim 13 (depends on 1) The vehicle according to claim 1, wherein the heating device is arranged in a footwell region of the vehicle. ### Claim 14 (depends on 1) The vehicle according to claim 1, wherein the contact-protection device has at least one opening for passage of thermal radiation, wherein the at least one opening is configured so that human appendages cannot be inserted into the opening. ### Claim 15 (depends on 1) The vehicle according to claim 1, wherein the reflector has a metallic surface. ### Claim 16 (depends on 2) The vehicle according to claim 2, wherein the heat source has a temperature of more than 150° C. ### Claim 17 (depends on 15) The vehicle according to claim 15, wherein the metallic surface is polished. ### Claim 18 (depends on 1) The vehicle according to claim 1, wherein the rearward reflector is arranged directly on a rear side of the contact-protection device. ### Claim 19 A heating system, comprising: a heating device having: an electrically operated heat source, and a reflector configured to reflect thermal radiation output by the heat source in a direction of a passenger compartment of a vehicle; a contact-protection device, wherein the contact-protection device is permeable to radiation so that the thermal radiation output by the heat source, or reflected by the reflector, is emitted into the passenger compartment, wherein the heat source and the reflector are arranged on a side of the contact-protection device, and the side is averted from the passenger compartment; and a rearward reflector arranged between the heating device and the contact-protection device, wherein the rearward reflector has a rear side that faces the heating device. ### Claim 20 A method for heating a passenger compartment of a vehicle, the vehicle including a heating device, a contact-protection device, and a rearward reflector, the method comprising the acts of: activating an electrically operated heat source of the heating device; and reflecting thermal radiation output by the heat source in a direction of the passenger compartment of the vehicle; wherein the contact-protection device is permeable to radiation so that the thermal radiation output by the heat source, or reflected, is emitted into the passenger compartment, wherein the heat source and the reflector are arranged on a side of the contact-protection device, and the side is averted from the passenger compartment, wherein the rearward reflector is arranged between the heating device and the contact-protection device, and wherein the rearward reflector has a rear side that faces the heating device.
