Body Protective Clothing

Abstract

Body protective clothing, comprising a hard shell ( 2 ) for covering the body part to be protected and an impact protection ( 10 ) arranged at the inside of the body protective clothing, the impact protection ( 10 ) comprising an impact absorbing foam enclosed by an airtight casing and at least one valve ( 16, 16 ′) arranged at the airtight casing, wherein the valve ( 16, 16 ′) is realized as a pressure relief valve in such a way that the compression of the impact protection ( 10 ) caused as a result of a crash opens the valve ( 16, 16 ′) for pressure reduction in the impact protection ( 10 ).

1 ) Body protective clothing, comprising a hard shell for covering the body part to be protected and an impact protection arranged at the inside of the body protective clothing, the impact protection comprising an impact absorbing foam enclosed by an airtight casing and at least one valve arranged at the airtight casing and capable of letting air escaping from said airtight casing, wherein the valve being realized as a pressure relief valve configured so as to open only from a predefined overpressure in said impact protection in such a way that the compression of the impact protection caused as a result of a crash opens the valve for pressure reduction in the impact protection. 
     
     
         2 ) Body protective clothing according to  claim 1 ), wherein an inlet valve is arranged at the airtight casing. 
     
     
         3 ) Body protective clothing according to  claim 1 ), wherein the inlet valve being realized in such a way that it absorbs air by means of a low pressure in the impact protection. 
     
     
         4 ) Body protective clothing according to  claim 1 ), wherein the impact absorbing foam has a shape memory function realized in such a way that the impact protection of the body protective clothing after use expands at least essentially to its original form. 
     
     
         5 ) Body protective clothing according to  claim 1 ), wherein the inlet valve and the valve for pressure reduction are realized as a single common valve. 
     
     
         6 ) Body protective clothing according to  claim 1 ), wherein the impact protection has several chambers, a plurality of these chambers being filled with the impact absorbing foam. 
     
     
         7 ) Body protective clothing according to  claim 6 ), wherein at least a plurality of these chambers, preferably all of them, are interconnected with each other with an air conduit system. 
     
     
         8 ) Body protective clothing according to  claim 6 ), wherein several of the chambers of the impact protection have a valve for pressure reduction as a result of a compression of the relative chamber of the impact protection and/or an inlet valve. 
     
     
         9 ) Body protective clothing according to  claim 1 ), wherein a further impact absorbing layer, preferably of polystyrene, is arranged between the hard shell and the impact protection. 
     
     
         10 ) Body protective clothing according to  claim 1 ), wherein the impact absorbing foam consists of polyurethane. 
     
     
         11 ) Body protective clothing according to  claim 1 ), wherein the hard shell comprises synthetic material, preferably polyurethane or an elastomer, and/or titanium and/or aluminum. 
     
     
         12 ) Body protective clothing according to  claim 1 ), wherein the hard shell comprises glass fibers and/or carbon fibers. 
     
     
         13 ) Body protective clothing according to  claim 1 ), wherein fixing means for fixing the body protective clothing, preferably to the body part to be protected, and/or device for adapting the fit to the body part to be protected is or are arranged at the body protective clothing. 
     
     
         14 ) Body protective clothing according to  claim 1 ), wherein means for aeration are arranged in the body protective clothing. 
     
     
         15 ) Body protective clothing according to  claim 1 ), wherein the body protective clothing is realized as a helmet.
