Abstract
Abstract A vehicle seat, more particularly aircraft seat, includes a seat bottom and a seat back disposed in a seat frame. The seat bottom can be folded down from a first near vertical position (I) into a second near horizontal position (II). This results in a comparatively simple, lightweight construction featuring good accessibility to several vehicle seats configured abreast and/or in rows.
