Abstract: An interior rearview mirror for vehicles has a housing having an interior. A mirror support has a first end and a second end, wherein the housing is connected to the first end of the mirror support and wherein the first end projects into the interior of the housing. A mirror pane is mounted in an opening of the housing. A switching member is mounted in the interior of the housing and is pivotable on the first end of the mirror support. An adjusting lever is mounted in the housing and projects from the housing. At least one spring is configured to act on the adjusting lever. The adjusting lever is movable against a force of the at least one spring and acts on the switching member for pivoting the mirror pane from a normal viewing position into a non-glare position. The switching member receives the force of the at least one spring exerted onto the adjusting lever and thus prevents deformation of the housing.

Abstract: A release element for a holddown device, on a solar generator, for example, with a retaining bolt which is under pretension in the direction of its lengthwise axis, releases the retaining bolt from its pretensioned position. Pretensioning force is exerted on the retaining bolt through thread located at the end of retaining bolt into a corresponding internal thread in the release device. Internal thread is located half in a housing of release device and half in an opener. Opener is inserted pivotably in a cutout of housing and held in place by a wire coil wound around housing and opener. To release retaining bolt, the wire coil is released by fuse elements and expands to a larger diameter, releasing the retaining bolt.
