Abstract

Applicable for all applications where air cells have to be fixed/attached to a (felt) backing sheet. The PU clip solution offers a 2-stage-attachment-possibility, designed as 2 bite-rings, to attach both foil to felt and felt to felt (allowing the fixation of felt carrier around seat flex mat wires to itself).

Applicable for all applications where air cells have to be fixed/attached to a (felt) backing sheet. The PU clip solution offers a 2-stage-attachment-possibility, designed as 2 bite-rings, to attach both foil to felt and felt to felt (allowing the fixation of felt carrier around seat flex mat wires to itself). thanks to dedicated bite ring distance adjusted to felt thickness, this solution offers a Poka-yoke for the closing of the felt flaps - either it is recognizably closed/fixed) or loose. With the current fir tree solution it is often unclear/undefined whether the flaps are properly pushed over the fir trees, depending on how many lamellas are in action. Thus, there is a certain risk that the part/assembly gets loose during seat lifetime, potentially leading to customer claims caused by reduced system function.

Due to its material nature, the PU clip is suitable to be welded directly to the foil. Welding is foreseen to one foil layer only, outside of air cell, not being used as spigot/air inlet into air cell. Welding it directly to air cell perimeter foil allows to skip later attachment process of fir tree clips. 1 process step less for picking part.

As an effect of the designated bite ring position, the PU clip can be significantly shorter than current fir tree clips. This reduced space consumption in the seat and significantly reduces risk of clip collision to adjacent parts, e.g. to back panel when seat is loaded and lumbar system get deflected rearwards....
