Claim 0:
1. A thermal insulation device adapted to be mounted to a vehicle, the vehicle defining a seating space therein and including a vehicle body that includes a bodyshell and a window that is mounted to the bodyshell, said thermal insulation device comprising:
a film unit being adapted to be mounted to the vehicle body for covering an inner surface of the window that faces the seating space, being light transmissive, and including an outer layer which is adapted to be mounted to the inner surface of the window, and an inner layer which is mounted to said outer layer such that said outer layer is disposed between said inner layer and the window, and which has a peripheral portion connected sealingly to said outer layer and a center portion spaced apart from and cooperating with said outer layer to define a thermal insulation space therebetween, said film unit being formed with a plurality of inlet holes that are in spatial communication with said thermal insulation space and that are adapted to communicate with the seating space, and a plurality of outlet holes that are in spatial communication with said thermal insulation space, that are disposed above said inlet holes, and that are adapted to be open toward the bodyshell, such that air in the seating space flows into said thermal insulation space through said inlet holes and is discharged from said thermal insulation space toward the bodyshell through said outlet holes, so as to ventilate said thermal insulation space; and
a thermal insulation unit including a heat insulation layer that is disposed on a side surface of said outer layer facing said thermal insulation space, and that is adapted to reflect and absorb heat conducted from the window.
