20080197613 | Rollover protection system for motor vehicles with a sensor-controlled actively deployable rollover body - The invention is based on a known rollover protection system for motor vehicles with a rollover body that is held guided in a holder affixed to the vehicle, a drive under spring tension for sensor-controlled deployment of the rollover body from a resting position to a protective position, and a locking device for the rollover body when deployed in the protective position. In order to create a very simple, low-cost and yet highly effective locking device, i.e. a block against retraction of the roll bar after a deployment due to an accident, the invention provides a detent pawl arrangement articulated in a pivoting manner and affixed to the vehicle and under spring tension in the locking direction by a retaining spring, with two extensions extending at least across the width of the rollover body, that in the protective position of the rollover body can be pivoted into direct active contact with corresponding supports on the rollover body. | 08-21-2008 |
