First Claim
1. A cushion part for at least one of a lower seat part and a backrest of a vehicle seat comprising:
- an elastic cushion base part having a thickness;
a plurality of holes extending through the cushion base part, each of the plurality of holes having a length equal to the thickness of the cushion base part and a diameter that is between approximately one-half and one-third the length of the aperture; and
an air-permeable air-conditioning layer arranged flat on the base part, the air- conditioning layer including a lower layer facing the base part and an upper layer lying on the lower layer;
wherein the cushion base part and the air-conditioning layer are configured to passively exchange at least one of heat and moisture.

Abstract
The invention relates to an upholstered element (1) for a lower seat part (2) and/or a backrest (4) of an air-conditioned motor-vehicle seat (6), comprising an elastic upholstered air-permeable base part (8) and an air-permeable air-conditioning layer (10) which is disposed on the surface of the base part (8). The air-conditioning layer (10) consists of at least two partial layers (14, 16), i.e. a lower layer (14) which is oriented towards the base part (8) and an upper layer (16) which is disposed on top of the lower layer (14). The upper layer (16) is made of a material which absorbs moisture. Preferably, an intermediate layer (22) made of an air-permeable material is disposed between the base part (8) and the lower layer (14). The lower layer (14) is relatively softer and the intermediate layer (22, 22a) is relatively harder, whereby the lower layer (14) and intermediate layer (22) are prevented from being pressed into holes (18) in the base part (8) when the seat is occupied.

26. A cushion part for at least one of a lower seat part and a backrest of a vehicle seat comprising:
-
an elastic cushion base part having a seat surface and including at least five holes distributed substantially evenly over the seat surface, the at least five holes extending through the cushion base part; and an air-permeable air-conditioning layer arranged flat on the base part, the air-conditioning layer including a lower layer facing the base part and an upper layer lying on the lower layer; wherein the at least five holes are configured to allow for the exchange of at least one of heat and moisture in the absence of a fan, by way of excitation from the movement of an occupant on the cushion part of the vehicle seat.
