Abstract
A non-slip high chair cushion, having globules C of rubbery polymeric material deposited on a scrim fabric A as by dipping same in a plastic foam material, prevents an infant from sliding forwardly out of the high chair.
Claims7
A non-slip cushion for a seat comprising a single layer of scrim fabric having spaced fibers extending longitudinally and transversely so as to possess substantial resistance to stretching in directions at right angles to each other;
- said scrim fabric having enlarged substantially rectangular openings therein formed by said longitudinally and transversely extending spaced fibers;
- globules of a rubbery polymeric material deposited on both sides of said scrim fabric providing each side thereof with a frictional coating of plastic foam material;
- said coated scrim fabric being configured to conform to the shape of a seat and positioned thereon to provide a cushion for a user of the seat;
- said cushion being breathable and flexible so as to lie flat against the seat surface under the weight of a user and maintaining a high coefficient of friction between one side of said cushion and said seat, and on the other side between said cushion and a user sitting on said cushion;
- said single layer of fabric being oriented in said cushion so that said scrim is in respective transverse and longitudinal alignment on said seat;
- and, said scrim fabric having a peripheral portion providing a border, edge including a binder, said binder being extended to form ties at one end of said cushion for securement to a chair back;
- whereby the user is protected against sliding and skidding off the seat and the cushion is protected against stretching under the weight of the user.

A method of using a non-slip cushion material for use as a supporting surface comprising the steps of:
- using a single-layer of a non-slip fabric made of scrim fabric having spaced fibers extending longitudinally and transversely so as to possess substantial resistance to stretching in directions at right angles to each other and providing enlarged openings therein, and having globules of rubbery polymeric foam material coated on both sides of said scrim so as to be flexible and breathable and to provide each side of said fabric with a friction surface;
- orienting said fabric so that said scrim fibers are disposed in transverse and longitudinal alignment on a supporting surface;
- cutting said fabric to form a cushion having a border portion defined by a peripheral edge and configured to conform to the supporting surface of a seat upon which the cushion is to be used, said border portion including a binder secured by stitches about the peripheral edge of the cushion, said binder being extended to form ties at one end of said cushion;
- placing said cushion on the supporting surface of a chair;
- and
- tying the ties to the back of the chair, whereby a person seated on said cushion is protected against sliding and skidding off the supporting surface.

A method of using a non-slip cushion material for use on a supporting surface comprising the steps of:
- using a single layer of a non-slip fabric made of scrim material spaced longitudinally and transversely having enlarged open gaps therein formed in a generally checkerboard pattern by said scrim, possessing substantial resistance to deformation in two directions at right angles to each other;
- providing enlarged open gaps in said fabric formed by said scrim and having globules of rubbery plastic foam material coated on said scrim so as to be flexible and breathable and to provide a first non-slip surface across one side of said fabric overlying said supporting surface, and a second non-slip surface across the other side of said fabric;
- orienting said fabric so that said scrim is disposed in transverse and longitudinal alignment on said supporting surface;
- forming a border about edges of said fabric to define a shape of said cushion conforming to a supporting surface upon said cushion used;
- orienting said border for transverse and longitudinal alignment with said supporting surface and for transverse and longitudinal alignment with said generally checkerboard pattern formed by said scrim;
- and
- placing said fabric on said supporting surface;
- whereby said cushion is secured to said supporting surface, and a person seated on said fabric is protected against sliding or skidding off of said supporting surface, and the cushion is protected against stretching under the weight of the user.
