Benefits of technology
"The present invention is an air distribution system for vehicles seats that is easy to install and secure. The system includes an air distribution layer and a first layer with a flange that sticks out from the air distribution layer. The flange has an adhesive area that sticks to the seat pad during assembly. The air distribution layer can have a recess that matches the size and depth of the flange. The system can be positioned within the recess and fixed to the seat pad using the adhesive. The invention provides an economical and accurate air distribution system that is easy to handle and position during seat manufacturing."
Problems solved by technology
Such seats are very costly to fabricate, since several layers must be sewn up, at least in part, successively.
Such operations are time consuming and inefficient.
Furthermore, positioning the ventilating layer on the pad poses difficulties in terms of accuracy.
This arrangement has disadvantages, too, as such parts may slip or require separate fastening elements.

Embodiment Construction
[0019] While the present invention is described with respect to an air distribution system for a vehicle seat, the present invention may be adapted and utilized for other ventilated components such as arm rests, door trim, armature panels as well as non-automotive seat and ventilated components applications. In the following description, various operating parameters and components re described for two embodiments. These specific parameters and components are included as examples and are not meant to be limiting.
[0020]FIGS. 1 and 2 show a cross-section and longitudinal section, respectively, of a component 30 in the passenger compartment of a vehicle, in this case a seat 31. A pad 6 is provided in the seat 31. The pad 6, on its side facing the passenger, comprises a recess 35. The recess 35 is bounded by pad elevations 41. On the side of the pad elevations 41 away from the recess 35, depressions 7 are provided. The recess 35 and the pad elevations 41 are provided in a first pad zone...

An air distribution system (20) for distributing air through a vehicle component such as a vehicle seat pad (6). The system (20) includes an air distribution layer (4) defining a base area and a first layer (2) arranged on the air distribution layer (4). The first layer (2) projects beyond the base area along at least a portion of an edge thereof to form a flange (25). A side of the flange (25) facing towards the air distribution layer (4) includes an adhesion area (5). During assembly, the adhesion area (5) engages the seat pad (6) along a pad elevation (41) surrounding a portion of the recess (35) formed in the seat pad (6) to fix the air distribution system (20) within the seat pad (6).
Description
TECHNICAL FIELD [0001] The present invention relates to an air distribution system for a vehicle component having an air distribution layer and an accompanying layer thereon. Such arrangements are employed, for example, in air-conditioned seats, to distribute air in the seating surface underneath a seat covering and thereby direct the flow towards a passenger. BACKGROUND OF THE INVENTION [0002] U.S. Pat. No. 5,902,014 discloses air-conditioned seats in which a ventilating layer made of a highly porous air-permeable material is sewn between a seat pad and a covering. In another example, DE 197 26 810 provides an areal heating element between such a ventilating layer and the covering. Such seats are very costly to fabricate, since several layers must be sewn up, at least in part, successively. Such operations are time consuming and inefficient. Furthermore, positioning the ventilating layer on the pad poses difficulties in terms of accuracy. [0003] EP 1,352,780 discloses a seat in whi...
