TECHNICAL AREA

The invention relates to a vehicle seat with a shielding device according to the preamble of claim 1. It also relates to a vehicle, in particular a motor vehicle, with at least one such vehicle seat.

BACKGROUND OF THE INVENTION

Autonomous driving places new demands on vehicle seats. Reclining seats for autonomous driving are already under development and in future will give customers the option of sleeping in the vehicle while driving. To do this, however, it is necessary to offer the sleeping vehicle passenger, in particular, an ambience that is hidden from view, so that he can feel comfortable and would also like to go to sleep. In particular when several people are sitting in a vehicle, there is no possibility of partitioning off the individual vehicle passengers.

STATE OF THE ART

From the DE 195 41 567 C1 a vehicle seat with an armrest is known in which a partition made of a foldable or rollable material can be pivoted out of the armrest in a fan-like manner around a rear pivot point close to the backrest towards the seatback. This partition forms a screen for a passenger sitting on the vehicle seat against unwanted looks from the side. It is also known from this to pivot an awning-like partition wall in the form of a hood over the head and shoulder area of the passenger on the upper edge of the backrest of the vehicle seat. The side partition and the awning-like partition can be operated independently of one another and are not connected to one another in any way.
