Abstract
A scissor drive includes two legs which can be pivoted relative to one another about a pivot axis, each having a longitudinal axis and designed to be connected to an external component, and a motor/gear assembly that drives the relative pivoting movement of the two legs. The first leg includes a housing that is hollow at least in portions, a cavity defined in the hollow housing extending at least in portions along the longitudinal axis of the first leg, and the motor/gear assembly being received in the housing of the first leg at least in portions in the portion of the cavity that extends along the longitudinal axis of the first leg.

Scissor drive, comprising:
- two legs which can be pivoted relative to one another about a pivot axis, each having a longitudinal axis extending between a free end and a pivot end, the pivot end being distal to the free end, each of the two legs being designed to be connected to an external component at the free end and to each other at the pivot end,
- a rotary motor that drives the relative pivoting movement of the two legs, the rotary motor having a rotational axis which extends substantially in parallel with the longitudinal axis of a first leg of the two legs,
- a planetary gear train located at the pivot end of each of the two legs, and
- a worm gear operatively connecting the rotary motor to the planetary gear train, and which is designed to convert a rotational movement of the rotary motor into a relative pivoting movement between the two legs;
- wherein:
- the first leg comprises a hollow housing,
- a cavity is defined in the hollow housing, the cavity extending along the longitudinal axis of the first leg, and
- the rotary motor is received in the cavity.
