Seat with seat sensor

Abstract

A seat with a seat sensor includes a soft pad having a cavity extending upwardly from a bottom surface thereof, a pressure sensitive sheet sensor for sensing a person sitting on the pad, and a soft material disposed in the cavity such that the soft material is prevented from coming off from the cavity. The sheet sensor is disposed on an upper portion of the soft material.

1 - 2 . (canceled) 
   
   
       3 . A seat with a seat sensor, comprising:
 a soft pad having a cavity extending upwardly from a bottom surface thereof,   a pressure sensitive sheet sensor for sensing a person sitting on the pad, and   a soft material disposed in the cavity such that the soft material is prevented from coming off from the cavity, said sheet sensor being disposed on an upper portion of the soft material.   
   
   
       4 . A seat with a seat sensor according to  claim 3 , wherein said cavity has a lower portion narrower than an upper portion so that the soft material is held in the cavity. 
   
   
       5 . A seat with a seat sensor according to  claim 3 , wherein a protrusion is formed around the cavity so that the soft material is prevented from coming off from the cavity. 
   
   
       6 . A seat with a seat sensor according to  claim 5 , wherein the protrusion is formed around an opening of the cavity. 
   
   
       7 . A seat with a seat sensor according to  claim 3 , wherein said soft material is held in the cavity such that the soft material is elastically pressed, to thereby prevent the soft material from coming off from the cavity. 
   
   
       8 . A soft pad for a seat with a seat sensor to which a pressure sensitive sheet sensor for sensing a person sitting on the pad is installed, said soft pad having a slit for inserting the sheet sensor, said slit extending from a side surface of the pad to a center of the pad. 
   
   
       9 . A soft pad for a seat with a seat sensor to which a pressure sensitive sheet sensor for sensing a person sitting on the pad is installed, said soft pad having a cavity extending upwardly from a bottom surface of the pad for inserting the sheet sensor, and a soft material inserted into the cavity such that the soft material is prevented from coming off from the cavity and the seat sensor is disposed on the soft material. 
   
   
       10 . A soft pad according to  claim 9 , wherein said cavity has a lower portion narrower than an upper portion so that the soft material is prevented from coming off from the cavity. 
   
   
       11 . A soft pad according to  claim 9 , wherein a protrusion is formed around the cavity so that the soft material is prevented from coming off from the cavity. 
   
   
       12 . A soft pad according to  claim 11 , wherein the protrusion is formed around an opening of the cavity. 
   
   
       13 . A soft pad according to  claim 11 , wherein said soft material is held in the cavity such that the soft material is elastically pressed, to thereby prevent the soft material from coming off from the cavity.
