Description

The invention relates to a mirror arrangement for a vehicle and to a vehicle comprising the mirror arrangement. Mirror arrangements for vehicles are known in a wide variety of configurations from the prior art. To individually adapt to different drivers, and in particular to ensure an optimal field of vision at all times, the mirrors in such arrangements are typically pivotable around both a horizontal and a vertical axis. Often, this adjustment is achieved by pivoting the mirror relative to a housing in which it is located. To enable this pivoting motion, sufficient clearance and complex kinematics are required, resulting in comparatively large mirror arrangements. It is therefore an object of the present invention to provide a mirror arrangement for a vehicle which allows a compact and simple construction with flexible adjustability. This problem is solved by the features of the independent claim. The dependent claims relate to advantageous embodiments of the invention. The problem is thus solved by a mirror arrangement for a vehicle, comprising a mirror unit, a first support arm connected to the mirror unit at a first mounting point, and a second support arm connected to the mirror unit at a second mounting point. The mirror unit is rotatable about a first axis of rotation relative to the two support arms. The two mounting points lie on the first axis of rotation. Furthermore, the first support arm is movable relative to the second support arm, so that the mirror unit is pivotable about a second axis of rotation, on which the second mounting point lies, relative to the second support arm. The first and second axes of rotation are perpendicular to each other. In particular, the first and second axes of rotation intersect at the second mounting point. The two mounting arms allow for a particularly lightweight and compact mirror unit with a maximum reflective surface area, while the swivel function of the mirror unit enables full adjustability. In other words, the special design of the mirror assembly incorporates an adjustment mechanism outside the unit itself, allowing it to swivel around its two axes. This keeps the mirror unit as compact as possible and results in a particularly low weight. Furthermore, this design frees up more installation space for the two mounting arms, allowing them to be attached to the vehicle body at a distance from each other, thus providing exceptional rigidity and robustness to the mirror assembly. Preferably, the mirror unit includes a mirror. For example, the mirror can be embedded in a frame or a housing. In particular, the mirror arrangement is a side mirror arrangement, which can be provided on the side of a vehicle, for example on the body or on a vehicle door. Specifically, the first axis of rotation is arranged vertically, and the second axis of rotation is arranged horizontally. Preferably, the first support arm is designed in two parts, comprising a support arm and a pivot arm that can be swivelled relative to the support arm. The first attachment point is located on the pivot arm. In particular, the movement of the first support arm relative to the second support arm, which causes the mirror unit to pivot about the second axis of rotation, is achieved by pivoting the swivel arm relative to the support arm. For example, the support arm can be fixed to the vehicle body and, in particular, immovable relative to the second support arm. The two-part design of the first support arm offers a particularly simple and cost-effective way to implement the desired adjustability of the mirror unit. Preferably, the swivel arm and the support arm are pivotably connected to each other about a pivot axis. The pivot axis is located between the first axis of rotation and an end of the first support arm opposite the first mounting point. In particular, the pivot axis and the first axis of rotation are thus arranged at a predefined distance from each other. This arrangement is especially advantageous when the support arm and the second mounting arm are fixed in position. By pivoting the swivel arm about the pivot axis relative to the support arm, the mirror unit is pivoted about the second axis of rotation. In particular, the pivotability of the mirror unit is limited by this design, for example, to a maximum pivot angle of up to 30°. This pivot angle is specifically dependent on a ratio of the first distance of the first mounting point. The first distance is from the pivot axis to a second distance between the two mounting points. Preferably, the first distance is at least 50% of the second distance to allow optimal pivoting of the mirror unit. Preferably, the pivot axis is parallel to the first axis of rotation. This allows the pivot arm to be designed, for example, simply and cost-effectively as a straight, plate-shaped lever that connects the support arm and the mirror unit. Preferably, the pivot arm and support arm can be connected to each other by means of a simple axial bearing.
