Bath tub cushion

Abstract

A bath tub cushion for lining one end surface and a portion of a bottom surface of a bath tub includes a back portion having a number of fluid impermeable chambers formed therein. A fluid communication device is disposed in fluid communication with an interior portion of the chambers for inflating and deflating them as necessary. An anti-slip mechanism is disposed on a back surface of the back portion which engages an end of such bath tub to prevent movement during use. A bottom portion extends toward an opposed end of such tub and is connected to a bottom edge of a front portion of such back portion for supporting a person's hips during bathing. There is an additional anti-slip mechanism disposed on a bottom surface of the bottom portion which engages bottom surface of such bath tub for preventing movement of the bottom portion during use.

1 . A bath tub cushion for lining at least one predetermined end surface and at least a portion of a substantially horizontally disposed bottom surface of a bath tub, said bath tub cushion comprising:
 (a) a back portion, having each of a first predetermined width, a first predetermined length, a first predetermined shape and a predetermined number of fluid impermeable chambers formed therein, disposed adjacent such predetermined end surface of such bath tub;   (b) a first means disposed in fluid communication with an interior portion of said predetermined number of said fluid impermeable chambers formed in said back portion for inflating and deflating chambers as necessary;   (c) a second means disposed on a back surface of said back portion and engageable with such substantially vertically disposed predetermined end of such bath tub for preventing movement of said back portion during use;   (d) a bottom portion extending toward an opposed end of such bath tub and connected to a bottom edge of a front portion of said back portion for supporting a person's hips during bathing in such bath tub, said bottom portion having each of a second predetermined width, a second predetermined length and a second predetermined shape; and   (e) a third means disposed on a bottom surface of said bottom portion and engageable with such substantially horizontally disposed bottom surface of such bath tub for preventing movement of said bottom portion during use.   
   
   
       2 . A bath tub cushion, according to  claim 1 , wherein said back portion further includes a plurality of raised portions having a third predetermined shape formed on a front surface of said back portion. 
   
   
       3 . A bath tub cushion, according to  claim 2 , wherein said first predetermined shape is each of generally rectangular when viewed from both front and back and generally triangular when inflated for use and generally rectangular when deflated for storage when viewed from a side. 
   
   
       4 . A bath tub cushion, according to  claim 3 , wherein said third predetermined shape is generally rectangular and having a rounded contour adjacent each outer corner thereof. 
   
   
       5 . A bath tub cushion, according to  claim 1 , wherein said predetermined numbers of fluid impermeable chambers is at least four. 
   
   
       6 . A bath tub cushion, according to  claim 1 , said fluid is air and first means for inflating and deflating chambers as necessary is an air inlet valve. 
   
   
       7 . A bath tub cushion, according to  claim 6 , wherein said air inlet valve is a two way check valve. 
   
   
       8 . A bath tub cushion, according to  claim 1 , wherein said second means for preventing movement of said back portion during use is selected from the group consisting of a rubberized coating and at least one suction cup. 
   
   
       9 . A bath tub cushion, according to  claim 8 , wherein said second means for preventing movement of said back portion during use is a plurality of suction cups. 
   
   
       10 . A bath tub cushion, according to  claim 1 , wherein said second predetermined shape of said bottom portion is generally rectangular. 
   
   
       11 . A bath tub cushion, according to  claim 10 , wherein said second predetermined length is less than said second predetermined width. 
   
   
       12 . A bath tub cushion, according to  claim 11 , wherein said third means for preventing movement of said bottom portion during use is selected from the group consisting of a rubberized coating and at least one suction cup. 
   
   
       13 . A bath tub cushion, according to  claim 12 , wherein said third means for preventing movement of said bottom portion during use is a plurality of suction cups. 
   
   
       14 . A bath tub cushion, according to  claim 1 , wherein said bottom portion includes at least one of padding disposed therein and a fluid impermeable chamber. 
   
   
       15 . A bath tub cushion, according to  claim 14 , wherein said bottom portion includes padding disposed therein. 
   
   
       16 . A bath tub cushion, according to  claim 1 , wherein head support and back support of said bath tub cushion are adjustable by adjusting an amount of fluid pumped into said predetermined number of said fluid impermeable chambers. 
   
   
       17 . A bath tub cushion, according to  claim 16 , wherein said predetermined number of said fluid impermeable chambers is at least four.
