  • Patent number: 8733823
    Abstract: A bumper system for a motor vehicle includes a bumper cross member which is arranged transversely to a travel direction and has two attachment zones for connection to two side rails arranged in parallel relationship to the travel direction. The bumper cross member has a center portion extending between the attachment zones and two end zones to close off the bumper cross member to vehicle sides. A deformation element is arranged behind each of the end zones and constructed to support in the event of a head-on collision with slight overlap the end zone which undergoes a buckling as a result of the head-on collision. At least one belt element at least partly surrounds a circumference of the deformation element and is secured to at least one of the side rails.

  • Patent number: 7481458
    Abstract: The present invention relates to a roll-over protection device for a motor vehicle, particularly for a convertible, comprising a roll bar (2). This roll bar is provided with an at least nearly U-shaped design having a transverse yoke (3) and lateral limbs (4A, 4B) while leaving a loading opening (11) unobstructed, and extending such that it essentially spans the width of the vehicle. The lateral limbs (4A, 4B) can be displaced along fixed guiding devices (6, 7) in order to transfer the roll bar (2) out of a lowered non-operational position and into a raised supporting position. To this end, a central retaining and activating device (12) for the roll bar (2), said device being controlled by an actuator (18), is provided and/or a device (17) that synchronizes the displacement of the limbs (4A, 4B) of the roll bar (2) along the guiding devices (6, 7) is provided.
