Patent ID: 7971693

Claim:
A damper ( 12 ; 12 a ; 12 b ), comprising: a. a casing ( 13 ; 13 b ) which has a central longitudinal axis ( 14 ); b. a tappet ( 15 ; 15 b ) which is displaceable in the casing ( 13 ; 13 b ) in a direction of the central longitudinal axis ( 14 ) and is extended out of the casing ( 13 ; 13 b ); c. first and second fastening elements ( 16 , 19 ; 16 b , 19 b ), wherein the second fastening element ( 19 ; 19 b ) is mounted on a free end of the casing ( 13 ; 13 b ;) and wherein the first fastening element ( 16 ;) is mounted on a free end of the tappet ( 15 ; 15 b ); and d. a frictional damping unit ( 32 ; 32 a ; 32 b ) which is disposed inside the casing ( 13 ; 13 b ), producing damping action, comprising: i. at least one piston ( 33 ; 33 a ; 33 b ) which is displaceable in relation to the casing ( 13 ; 13 b ) and the tappet ( 15 ; 15 b ) in the direction of the central longitudinal axis ( 14 ), said at least one piston ( 33 ; 33 a ; 33 b ) comprising at least two neighboring wedges ( 40 ); ii. at least one frictional lining ( 36 ; 36 b ) which is partially enclosed by the at least one piston ( 33 ; 33 a ; 33 b ); iii. at least one stop element ( 45 , 46 ; 45 b , 46 b ) for limitation of the motion of the at least one piston ( 33 ; 33 a ; 33 b ) in the direction of the central longitudinal axis ( 14 ) by striking against the at least one stop element ( 45 , 46 ; 45 b , 46 b ); iv. at least one buffer stop ( 54 ; 54 a ; 54 b ) which is disposed between the at least one piston ( 33 ; 33 a ; 33 b ) and the at least one stop element ( 45 , 46 ; 45 b , 46 b ), damping the stop of the piston ( 33 ; 33 a ; 33 b ), the at least one buffer stop ( 54 ; 54 a ; 54 b ) having at least one flexibly pliable buffer stop element ( 55 ; 55 a ; 55 b ) which is in one piece with the at least one piston ( 33 ; 33 a ) and wherein the at least one flexibly pliable buffer stop element ( 55 ; 55 a ; 55 b ) is integral with one of said at least two wedges ( 40 ) of the piston ( 33 ; 33 a ; 33 b ) and wherein in a direction of the central longitudinal axis ( 14 ), the at least one flexibly pliable buffer stop element ( 55 ; 55 a ; 55 b ) stands out from a front wall ( 41 ) of said at least two neighboring wedges ( 40 ).
