Patent ID: 8176819

Claim:
A collision sensing device adapted to detect a collision between two or more objects, comprising: a deformable member ( 5 ) of elastically deformable material which defines a space ( 15 ) that assigned a pressure, which the deformable member ( 5 ) in a first condition is undeformed whereby the space ( 15 ) is assigned a first pressure (P 1 ), and wherein in a second condition the deformable member ( 5 ) is deformed whereby the space ( 15 ) is assigned a second pressure (P 2 ); wherein the deformable member ( 5 ), upon collision of the deformable member ( 5 ) with an object, is deformed into the second condition whereby the pressure in the space ( 15 ) changes from the first (P 1 ) pressure to the second pressure (P 2 ); and means ( 3 ) for detecting the pressure change.
