Document Type and Number:
WIPO Patent Application WO/2017/141435
Kind Code:
A1
Abstract:
This molded surface fastener (1, 2, 3, 4, 5) includes left and right resin intrusion prevention walls (20, 50, 60, 70, 80) that have a plurality of vertical wall rows (21, 51, 61a, 61b, 71a, 71b, 81a, 81b), each of which has a plurality of vertical wall portions (22, 52, 62, 72, 82) that are arranged intermittently at a predetermined pitch along the length direction. Each of the vertical wall portions (22, 52, 62, 72, 82) of each of the vertical wall rows (21, 51, 61a, 61b, 71a, 71b, 81a, 81b) is connected to two vertical wall portions (22, 52, 62, 72, 82) in another vertical wall row (21, 51, 61a, 61b, 71a, 71b, 81a, 81b) by connecting wall portions (23, 53, 63, 73, 83). The connecting length of the connecting wall portion (23, 53, 63, 73, 83) that connects the vertical wall portions (22, 52, 62, 72, 82) is set to be wider than the width dimension of the vertical wall portions (22, 52, 62, 72, 82). Thus, flexibility of the molded surface fastener is improved. In addition, engaging elements (12) of the molded surface fastener can be prevented from being embedded into foamed resin when a cushion body (10) is molded.
