PROTECTIVE DEVICE FOR A MOTOR VEHICLE

A protective device of this kind with a flexible sheet material that is held on a winding shaft and is displaceable between an extended protective position and a rest position wound up on the winding shaft, wherein the winding shaft is driven by a motor in both rotational directions, wherein the sheet material is provided at its front end region in the withdrawal direction with a shape-stable withdrawal profile, and wherein drive transmission means are provided that engage on the withdrawal profile and are in operative connection with the winding shaft, is known. According to the invention, the winding shaft is assigned a blocking device that, by means of a control device, is displaceable between a release position that releases the winding shaft for rotational movement and a securing position that blocks the winding shaft against rotational movement, depending on a displacement position of the withdrawal profile.
