The hinge arrangement allows the flap part to be pivoted about a first axis of rotation for opening and closing the vehicle flap and about a second axis of rotation for raising the vehicle flap into a pedestrian protection position. The drive device further includes a first actuator for opening and closing the vehicle flap in normal operation, a second actuator for raising the vehicle flap into a pedestrian protection position and a coupling device for coupling the first actuator to one of the flap part and the vehicle flap, including a fastening part which is fixedly connected to the one of the flap part and the vehicle flap. The coupling device includes at least one first lever coupled to the first actuator. During normal operation of the coupling device, the first lever is releasably secured against rotation relative to the fastening part via a mechanical securing element.

Abstract: A spring part, in particular for a driving device, includes a spring body extending around a central axis. The spring body comprises several spring windings which run radially around a spring axis and are made of at least a base material. The base material is surrounded at least by a first protective layer, and the spring body is at least partially covered on the outside by a lubricant. A method for manufacturing a spring part includes the steps of providing a spring body with several spring windings made of a base material and coating the base material at least with a first protective layer. The method includes the step of applying a lubricant formed as a silicone-based lubricant to the outside of the coated spring body.

Abstract: A drive device, in particular for an adjustable vehicle flap, comprising includes a housing extending axially along a drive axle, a motor for generating a driving force in the direction of the drive axle, a first drive element, and a coupling device arranged between the motor and the first drive element. The coupling device comprises a coupling housing and at least one first coupling part with a coupling section for coupling to the first drive element. The first drive element is coupled to the coupling device via the coupling section of the first coupling part, and a braking device for braking a drive movement of the first drive element. A drive device, in particular for an adjustable vehicle flap, which has a lower residual installation length and can thus be used more flexibly in various installation space situations is created by the braking device being arranged axially in the coupling section of the first coupling part.
