  • Patent number: 11007723
    Abstract: A method can be used to attach a fabric member to a trim while forming a pattern in the fabric member. A trim has trim grooves formed in one side of the trim and a fabric member has a foam formed in one side of a skin material of the fabric member. A bonding member is coated to an outer surface of the foam and the fabric member is heated where the bonding member is coated. The heated fabric member is placed on the side of the trim where the trim grooves are formed. The fabric member is fixed to the trim by inserting edges of the fabric member into the trim grooves using insertion blades while pattern protrusions formed in a compression jig form a pattern by pressing the skin material of the fabric member.
