Forming die for forming a vehicle seat foam cushion member with a pile-type fastener

#1. Field of the Invention

#The present invention relates to a forming die for forming a cushion member used in the seat of vehicle or automobile and so forth, and in particular relates to a forming die for forming a foam cushion member on its surface with a female pile-type fastener adapted to be engageable with a mating male one provided on the back surface of a top cover member associated with the seat.

#2. Description of the Prior Art

#FIG. 1 is a schematic view showing steps for forming a foam cushion member integrally with a pile-type fastener in accordance with the present invention;

#FIG. 2 is a sectional view of a foam cushion member to be produced by the method of the present invention and a top cover member which is to cover the cushion member;

#FIG. 3 is a sectional view of the principal portion in accordance with the present invention;

#Referring to FIG. 1, there is illustrated a process for forming a cushion member (A) integrally on its surface with a pile-type fastener (a), using a forming die (1) of the present invention.

#At first, a brief description will be given with regard to such process: Firstly, a corresponding number of pile-type fasteners as indicated by reference character (a) are at their hook portions (a1) engaged with the respective engageable members (2). Next, a liquid form of polyurethane (5) is injected into the forming die (1), and then after closing airtight the die (1), the liquid form of polyurethane (5) is subjected to a foaming process. Thereafter, the forming die (1) is opened and the resultant foam product is removed away therefrom, whereupon obtained is the cushion member (A) with the pile-type fasteners (a) on its surface.

#Now, the construction of the forming die (1) in accordance with the present invention will be described hereinafter.
