Seat for snowmobile or other similar vehicle

Abstract

Disclosed is a seat for snowmobile, personal watercraft or all terrain vehicle, which is filled of synthetic foam and extends horizontally over a given length and on which the user of the vehicle may seat astride. The seat is provided with a cavity that extends horizontally over at least one part of its length. The cavity is filled with an inflated inner tube that acts as an additional suspension for the user. The presence of this inner tube gives additional suspension effect and solves most of the problems of density and performance losses that are usually encountered when the seat is only filled up with synthetic foam. Preferably, the cavity provided within the seat has a length greater than the one of the inner tube so as to give extra space and thus allows the inner tube to expand in the case of an impact.

1 . A seat for snowmobile or other similar vehicle, said seat being of a given length and filled of synthetic foam and extending horizontally onto a rigid support, wherein said seat is provided with a cavity that extends horizontally over at least one part of its length and said cavity is filled with an inflated inner tube so as to provide additional suspension for a user.  
     
     
         2 . The seat according to  claim 1 , wherein the cavity within the seat has a length greater than the one of the inner tube in order to give some extra space and thus allow the inner tube to expand in a horizontal plane in the case of an impact.  
     
     
         3 . The seat according to  claim 1 , wherein the inner tube is held within a sleeve having at least one opened end, said sleeve preventing the inner tube from dilating in directions other than the longitudinal one in the case of an impact.  
     
     
         4 . The seat according to  claim 1 , further comprising a rear trunk that manually openable and is also mounted onto the rigid support of the seat, wherein the inner tube is provided with an air inlet tube which extends within the trunk and is closed by a valve which also extends within the trunk and to which an air pump can be connected.  
     
     
         5 . The seat according to  claim 4 , wherein the pump is connected to the valve in a permanent manner and sized to be stored within the trunk.  
     
     
         6 . The seat according to  claim 4 , wherein the valve is provided with a pressure gauge.  
     
     
         7 . The seat according to  claim 1 , wherein, in use, the inner tube is inflated at a pressure ranging from 0.75 to 2 psi.  
     
     
         8 . The seat according to  claim 2 , wherein the inner tube is held within a sleeve having at least one end open, said sleeve preventing the inner tube from dilating in direction over than the longitudinal one in the case of an impact.  
     
     
         9 . The seat according to  claim 8 , further comprising a rear trunk that manually openable and is also mounted onto the rigid support of the seat, wherein the inner tube is provided with an air inlet tube which extends within the trunk and is closed by a valve which also extends within the trunk and to which can be connected an air pump.  
     
     
         10 . The seat according to  claim 9 , wherein the pump is connected to the valve in a permanent manner and sized to be stored within the trunk.  
     
     
         11 . The seat according to  claim 10 , wherein the valve is provided with a pressure gauge.
