Abstract
A fastener element with a sheet-form base and an array of wedge-shaped engageable elements molded integrally with a surface of the sheet-form base. The wedge-shaped elements each have a steep side and a gradually rising side, and are arranged with their steep sides all directed in a common sense, such that the array can engage a similar array of oppositely-directed wedge-shaped elements to resist shear motion. The distal edges of the wedges are curved in top view.
Claims46
A seat bun, comprising:
- a compliant material with a surface having a central region bounded on two opposite sides by elongated trenches;
- and
- a fastener component disposed within each trench, the fastener component comprising a sheet-form base, and an array of wedge-shaped, engageable elements extending integrally from at least one side of the sheet-form base, the engageable elements each having an engageable side and a non-engageable side conterminous at an upper edge of the element, wherein the upper edge of each engageable element defines a curve in top view, wherein the engageable sides of a majority of the elements are oriented in a common direction, wherein the engageable side intersects an upper surface of the base and the non-engageable side extends from the base to the upper edge of the element, and wherein each fastener component is arranged with the non-engageable sides of its wedge-shaped elements directed out of the trench.
A self engageable fastener component, comprising:
- a sheet-form base;
- an array of wedge-shaped, engageable elements extending integrally from at least one side of the sheet-form base, the engageable elements each having an engageable side and a non-engageable side conterminous at an upper edge of the element, the engageable side intersecting an upper surface of the base and the non-engageable side extending from the base to the upper edge of the element;
- and
- hook-shaped projections proximate the wedge-shaped engageable elements, wherein the upper edge of each engageable element defines a curve in top view, and wherein the engageable sides of a majority of the elements are oriented in a common direction.

A self engageable fastener component, comprising:
- a sheet-form base;
- and
- an array of wedge-shaped, engageable elements extending integrally from at least one side of the sheet-form base, the engageable elements each having an engageable side and a non-engageable side conterminous at an upper edge of the element, the engageable side intersecting an upper surface of the base and the non-engageable side extending from the base to the upper edge of the element;
- and
- engageable loops proximate the wedge-shaped elements, wherein the upper edge of each engageable element defines a curve in top view, and wherein the engageable sides of a majority of the elements are oriented in a common direction.
2 more elements
A self-engageable fastener component, comprising:
- a sheet-form base;
- and
- an array of wedge-shaped, engageable elements extending integrally from at least one side of the sheet-form base and arranged in multiple rows, the engageable elements each having an engageable side and a non-engageable side conterminous at an upper edge of the element;
- wherein the upper edge of each engageable element defines a curve in top view;
- wherein the engageable sides of a majority of the elements are oriented in a common direction and overhang the sheet-form base to resist separation of a mating fastener element;
- wherein the engageable side intersects an upper surface of the base and the non-engageable side extends from the base to the upper edge of the element;
- and
- wherein pairs of adjacent fastener elements in each row define corresponding wells therebetween for receiving an upper edge of a mating fastener element.
