  • the back cushion is variable in its contour such that a contour of the back cushion in the lying position has a stronger, forward bulge than in the sitting position.
  • the bulge occurring in the lying position of the backrest causes a high degree of comfort of the vehicle seat in the lying position.
  • a "lying position” or “lying position” relative to a seat position or seat position of the vehicle seat is to be understood in particular as a position in which the back of a passenger located in the vehicle seat with a greater inclination relative to the vertical direction than in the sitting position or sitting position of Back pad is supported.
  • the vehicle seat has a leading edge formed by the seat cushion and extending in a lateral direction, which is arranged in a row in a vehicle,
  • a rail vehicle facing a front seat and / or facing away from a rear seat. It also has a seating direction, which is aligned horizontally and perpendicular to the lateral direction.
  • the sitting direction corresponds in particular to the orientation of the thighs a passenger assuming a normal sitting position with uncrossed legs. It is oriented starting from the back pad in the direction of the front edge.
  • the term "forward” here refers to a direction in which-with respect to a disassembly in the seat direction and the lateral direction-the largest component is oriented in the seat direction

  • At least the region of the bulge of the back pad may be supported by at least one support member between the back cushion and the frame, wherein the support member is changeable in position relative to the frame and the relative movement between the seat cushion and the backrest follows such that in the lying position the bulge is present.

Abstract

L'invention concerne un siège de véhicule, notamment pour les véhicules ferroviaires spacieux, qui est réglable entre une position assise (A) et une position allongée (B) et qui présente un rembourrage de siège (2) ainsi qu'un dossier (1) avec un rembourrage de dos (4), lesquels s'appuient respectivement sur un bâti (3). Selon l'invention, une transition entre la position assise (A) et la position allongée (B) en vue de modifier la forme extérieure du siège de véhicule s'effectue par un mouvement relatif du rembourrage de siège (2) par rapport au dossier (1) et le profil du rembourrage de dos (4) peut être modifié par une transposition du mouvement relatif entre le rembourrage de siège (2) et le dossier (1) de telle sorte qu'un profil du rembourrage de dos (4) présente, en position allongée (B), un bombement dirigé vers l'avant plus important qu'en position assise (A).
