  The present invention relates to a seat cushion, and more particularly to an auxiliary seat cushion on a toilet seat, a stool or a chair to assist an invalid to sit down with less effort and with safety and comfort. . A conventional raised toilet seat has been developed to help a disabled person, for whom it is difficult to use a regular toilet seat, to get up and sit down with less effort. Examples of some of these prior achievements are shown in US Pat. No. 5,027,445 to Locarno; in US Pat. No. 5,199,112 to Locarno; in U.S. Patent No. D 489,438 to Hunt. However, they are made of a rigid material, and as such are uncomfortable and dangerous to use for an invalid person in a slippery bathroom.

  There are also, in the prior art, cushioned seats developed for soft and comfortable toilet seats, as disclosed in U.S. Patent No. 3,949,432 to Ginsburg; U.S. Patent 4,248,646 to Ginsburg; U.S. Patent US D 390 644 in the name of Hicks; US Patent 5,991,935 in the name of Wang; U.S. Patent 6,330,723 to Orgias; US Patent 6,370,704 to White. Classic upholstered toilet seats are formed of three layers, namely a base; an insert disposed on the upper surface of the base; and an outer cover layer attached to the base. In principle, they are developed for a normal user. As a result, the focus has been on flexibility and comfort, so they are not suitable for a disabled person who needs a safer seat with less effort.

  Considering the prior state of the art above, the present invention relating to an auxiliary seat cushion may be useful to an invalid person, allowing him to sit down with less effort and with safety and comfort. The objects of the present invention are as follows: first, to provide a raised soft-touch cushion with some elasticity and plasticity to help an invalid to sit on a toilet seat, stool or chair, comfortably, safely and with less effort; secondly, to provide a watertight, ventilated, textured surface that is easy to maintain and wash and that prevents the user's skin from sweating and slipping; thirdly, at least one set of clamping device disposed on the lower portion of the auxiliary seat cushion, which is easy to operate and fix on a toilet bowl. Briefly, in accordance with a first preferred embodiment of the present invention, an auxiliary seat cushion comprises a support plate, a padding body, an envelope, and at least one clamping device. The detailed description of each part of said auxiliary seat cushion is as follows: The support plate is a rigid annular plate used as a base to support the weight of an invalid person, and able to cooperate with at least one clamping device. The padding body is made of a light, thick material, and deposited on said support plate, which allows the surface of the seat part to be raised so that an invalid can sit and bend the knees with a least effort. The envelope is made of a resilient foam material to surround said support plate and said pad body with a surface-ventilated texture, a goose-like texture providing a dry, non-slip contact for an invalid, and a waterproof material which is convenient to wash and clean being preferred. An inner peripheral flange of said envelope is introduced on said toilet bowl. The density of the padding body is advantageously opposite that of the casing; for example, there will be a lower density padding body surrounded by a higher density shell, or a higher density padding body, surrounded by a lower density shell. As a result, the auxiliary seat cushion provides flexibility and maintains a shape to allow an invalid to sit on it.

  At least one clamping device is disposed on the lower portion of said auxiliary seat cushion, which device is intended to be clamped on the outer edge of said toilet bowl. A locking member disposed on the lower front side of said auxiliary seat cushion cooperates to secure said auxiliary seat cushion to the upper portion of said toilet bowl. In a second preferred embodiment of the present invention, an auxiliary seat cushion, made in a rounded shape without a central hole to be deposited on a stool or chair, comprises three layers which correspond respectively to the rigid support plate, to the padding body and the casing of the first preferred embodiment.
