A hydraulic chair lift in a vehicle includes a rod that is attached to the floor and the roof of the vehicle, a piston that is arranged around the rod in a middle zone of the rod, a barrel that envelopes the piston, and two heads, each of which is arranged on an end of the barrel. Further, the two heads are provided with a channel for the passage of the rod. Additionally, a rod gland is arranged in each of the two heads surrounding the channel. Relative to the rod gland, the channel includes a first inner channel part with a first diameter and a second inner channel part with second diameter. The first diameter is smaller than the second diameter and the ratio of the length and the diameter of the first channel part is less than 3/5.
