Abstract:
1. A linear drive comprising a drive unit ( 40 ) and a sliding element ( 36 ) that are disposed in a frame ( 38 ), wherein the sliding element ( 36 ), actuated by the drive unit ( 40 ), is capable of effecting a movement in a direction of translation with respect to the frame ( 38 ), and having a blocking device for blocking the sliding element ( 36 ) with respect to the frame ( 38 ) in the event of a shock load to the sliding element ( 36 ), wherein the blocking device has a compensating body ( 18 ; 70 ; 88 ; 90 ; 94 ) coupled to the sliding element ( 36 ), the compensating body ( 18 ; 70 ; 88 ; 90 ; 94 ) being likewise exposed to the shock load and disposed such that an acceleration of the compensating body caused by the shock load counteracts an acceleration of the sliding element caused by the shock load.
