Molded surface fastener

摘要

A surface fastener member includes left and right longitudinal protective wall sections and front and rear lateral protective wall sections. Each of the lateral protective wall sections includes an outer first lateral wall section and an inner second lateral wall section. The first lateral wall section includes a continuous lateral wall body which is continuously placed between the left and right longitudinal protective wall sections at a predetermined height. The second lateral wall section includes a plurality of divided lateral wall bodies which are intermittently placed along a width direction, and a plurality of second engagement elements. According to this, when the molded surface fastener is integrally molded on a cushion body, it is possible to prevent resin material from entering an engagement element region of the surface fastener member.

主权项

1. A molded surface fastener comprising
surface fastener members in which a plurality of engagement elements stand on first surfaces of flat plate-shaped base materials, and flexible connecting portions which connect the plurality of surface fastener members to each other in a longitudinal direction, in which each of the surface fastener members comprises a pair of left and right longitudinal protective wall sections placed along the longitudinal direction on left and right side edge portions of the flat plate-shaped base materials in a width direction, and a pair of front and rear lateral protective wall sections placed on front and rear end edge portions of the flat plate-shaped base materials in the longitudinal direction, and the molded surface fastener is integrally molded on a surface of a cushion body when the cushion body is foamed and molded, wherein each of the lateral protective wall sections includes an outer first lateral wall section and an inner second lateral wall section, the engagement elements include first engagement elements placed in a region surrounded by the longitudinal protective wall sections and the second lateral wall section, and a second engagement elements directly placed in the second lateral wall section, the first lateral wall section comprises a continuous lateral wall body which is connected to the left and right longitudinal protective wall sections and which continuously stands at a predetermined height from the flat plate-shaped base materials between the left and right longitudinal protective wall sections, and the second lateral wall section comprises divided lateral wall bodies which are intermittently placed along the width direction between the left and right longitudinal protective wall sections, and the second engagement elements placed between the divided lateral wall bodies.
