Various embodiments of an attachment assembly are described herein. In particular, the embodiments described herein relate to an improved attachment assembly for securing the seat trim to the seat padding in trench attachment applications in a ventilated vehicle seat.
Ventilated vehicle seats can include a frame to support the seat and to mount it to a vehicle, padding to cover the frame and made, for example, of foam material, an air permeable spacer layer, and an outer layer of upholstery. The upholstery may be attached to the padding and/or the frame by any known attachment assembly, such as a trench attachment application. It would be desirable to provide an improved attachment assembly for securing the seat upholstery to the seat padding in trench attachment applications in a ventilated vehicle seat.
SUMMARYThe present application describes various embodiments of a ventilated vehicle seat. One embodiment of the ventilated vehicle seat includes one of a seat back and a seat cushion having an air transmission channel therethrough. Upholstery covers the one of a seat back and a seat cushion. An air permeable spacer layer is disposed between the one of a seat back and a seat cushion and the upholstery, and the air permeable spacer layer is in fluid communication with the air transmission channel. An air permeable tie-down strap connects the upholstery to the one of a seat back and a seat cushion.
Other advantages of the ventilated vehicle seat will become apparent to those skilled in the art from the following detailed description, when read in light of the accompanying drawings.
Referring now to the drawings, there is illustrated in
The seat cushion 12 and seat back 14 include a flexible trim material or upholstery 16. The upholstery 16 may be constructed of any desired material, such as natural or synthetic fabric or leather.
The seat cushion 12 may also include a cushion portion 13 and an air permeable spacer layer 18 disposed between the cushion portion 13 and the upholstery 16. Although the exemplary embodiment of the seat assembly 10 illustrated in
In the illustrated embodiment, the spacer layer 18 is within the range of from about five mm to about 14 mm thick. In another embodiment, the spacer layer 18 is within the range of from about four mm to about 24 mm thick. Alternatively, the spacer layer 18 may be any desired thickness. It will be understood that the optimum thickness for the spacer layer 18 will only be determined by routine experimentation and by considering the space available and the required air flow performance. The spacer layer 18 may be as thick as possible, and comprise as many layers of air permeable material as possible, so as to maximize the movement of air and the cooling of the seat cushion 12 and/or seat back 14. The spacer layer 18 may be attached to the seat cushion by 12 any desired means, such as for example with an adhesive or with hook-and-loop fasteners. It will be understood that no such attachment means are required.
The seat cushion 12 may also include one or more air transmission channels 20. Such an air transmission channel 20 may extend between a fan 22, as best shown in
If desired, an additional layer 24 may be disposed between the spacer layer 18 and the upholstery 16. For example, the additional layer 24 may be a heater mat. Alternatively, the additional layer 24 may be a second cushion or trim pad, which may be manufactured from a flexible foam material. Although the exemplary embodiment of the seat assembly 10 illustrated in
As best shown in
The seat assembly 10 further includes an air permeable tie-down strap 36, illustrated in
Referring again to
In the embodiment illustrated in
As best shown in
The anchor 42 is further attached to the tie-down strap 36 about the anchor portion 38. The anchor 42 may have any desired shape. For example, the illustrated anchor 42 includes a body portion 42A having a substantially rectangular cross-sectional shape, and an anchor portion 42B having a substantially T-shaped cross-sectional shape (inverted T-shape as viewed in
It will be understood that the tie-down strap 36 may be attached to the anchor 42 or may be attached directly to the cushion portion 13 by any means, such as for example, a hog-ring (not shown), with hook and loop fasteners (not shown), or any other suitable fasteners.
Advantageously, the seat assembly 10 is able to provide efficient and effective cooling of the seat occupant at an improved cost relative to known ventilated seats.
The principle and mode of operation of the improved ventilated vehicle seat have been described in its various embodiments. However, it should be noted that the ventilated vehicle seat described herein may be practiced otherwise than as specifically illustrated and described without departing from its scope.
