Method that forms pattern on fabric member and fixes pattern on trim

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.

(22) Referring to FIG. 4, the trim 200 is integrally formed. A method for molding the trim 200 refers to a known method.

(23) First, the fabric member 110 is cut into a predetermined shape using a cutter 400, and the bonding member 420 is coated to one side of the fabric member 110 using a bonding member coating device 410.

(24) In the exemplary embodiment of the present invention, the fabric member 110 includes the skin material 112 and a soft foam 114 formed at one side of the skin member 112, and the bonding member 420 is coated to an outer surface of the foam 114.

(25) In addition, the heater 470 heats the fabric member 110 coated with the bonding material 420 at a predetermined temperature, and the heated fabric member 110 is fixed to the trim 200 by using a first mold 431 and a second mold 432 and then the pattern is formed.

(26) Referring to the lower part of the flowchart in FIG. 4, a molding unit includes the first mold 431, the second mold 432, a compression jig 440, pattern protrusions 445, insertion blades 450, and the trim 200, and the fabric member 110 is disposed between the trim 200 and the compression jig 440.

(27) The compression jig is placed on the second mold 432, and the pattern protrusions 445 and the fixing protrusions 700 are provided at predetermined locations on an upper side of the compression jig 440.

(28) The pattern protrusion 445 presses the skin material 112 of the fabric member 110 during a press process such that a pattern is formed, and the fixing protrusions 700 press the outer surface of the fabric member 110 to closely attach the fabric member 110 to the trim 200.

(29) The insertion blades 450 that protrude upwardly are formed at opposite edges of the second mold 432, and penetrate the compression jig 400 and insert the opposite edges of the fabric member 110 into trim grooves 500 formed in the trim 200 such that the fabric 110 is fixed to the trim 200. Here, the trim 200 may be disposed in a bottom side of the first mold 431.

(30) In the exemplary embodiment of the present invention, the location of the first mold 431 and the location of the second mold 432 may be switched. That is, the first mold 431 may be disposed in the lower portion and the second mold 432 may be disposed in the upper portion.

(31) FIG. 5 is a cross-sectional view of a method for finishing the edge of the fabric member by fixing the edge to the trim according to the exemplary embodiment of the present invention.

(32) Referring to FIG. 5, the trim groove 500 is formed at the predetermined location in the trim 200, and when the insertion blade 450 presses the edge of the fabric member 110 while the fabric member 110 is attached to one side of the trim 200, the insertion blade 450 is inserted into the trim groove 500 together with the fabric member 110 such that the fabric member 110 is inserted into the trim groove 500 and then fixed thereto.

(33) FIG. 6 is a schematic cross-sectional view of a system that attaches the fabric member to the trim while forming a pattern in the fabric member according to the exemplary embodiment of the present invention.

(34) Referring to FIG. 6, the first mold 431 is disposed in the lower portion, and the trim 200 is placed on the first mold 431. Then, the fabric member 110 is disposed on the trim 200.

(35) The insertion blades 450 extend downwardly from the predetermined locations of the bottom of the second mold 432, and a heater 470 may be disposed in the bottom side of the second mold 432. The heater 470 disposed in the bottom side of the second mold 432 heats the fabric member 110 that is placed on the trim 200 at a predetermined temperature.

(36) Next, the compression jig 440 is injected between the heater 470 and the fabric member 110 such that the compression jig 440 is placed on the fabric member 110.

(37) FIG. 7 is a schematic cross-sectional view of a system that attaches a fabric member to a trim while forming a pattern in the fabric member according to another exemplary embodiment of the present invention.

(38) Referring to FIG. 7, when a first mold 431 moves down, insertion blades 450 penetrate a compression jig 440 and thus a fabric member 110 is fixed to a trim 200 by being inserted into trim grooves 500 of the trim 200, and pattern protrusions 445 formed in the compression jig 440 form a pattern in the fabric member 110. Then, fixing protrusions 700 press the fabric member 110 to prevent the fabric member 110 from being misplaced on the trim 200.

(39) Referring to FIG. 7, the compression jig 440 may be used during a cold engine state, but in order to form a pattern more in detail, a ultrasonic wave application unit 750 is connected to the compression jig 440 to apply a ultrasonic wave of a predetermined frequency when the compression jig 440 form a pattern.

(40) That is, the compression jig 440 may be used as a simple cold jig and is excellent for implementation of various patterns, but when the compression jig 440 is connected with the ultrasonic wave application unit 750 and compressed for implementation of a more detailed pattern, vibration of the compression jig 440 may occur.

(41) While this invention has been described in connection with what is presently considered to be practical example embodiments, it is to be understood that the invention is not limited to the disclosed embodiments. On the contrary, it is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
