Definitions
- the invention relates to a vehicle seat
- Back pad has, each on a frame
- the present invention seeks to produce a vehicle seat, which provides a high seating comfort for a passenger with little space in the longitudinal direction of the vehicle in its reclining position.
- 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
- Vehicle seat can be achieved, in which an area of the lumbar spine of a person using the passenger seat is supported.
- the convexity of the back pad present in the lying position of the vehicle seat is only present over a vertical portion of the back pad. This is basically sufficient for a suitable back support of a passenger.
- the present in the reclining position of the vehicle seat bulge of the back pad in the vertical direction continuously
- any relative movement between seat cushion and backrest can be used to provide suitable
- Implementation agent bring about the bulge of the back cushion in the lying position. However, in one embodiment, to facilitate the relative movement between
- the seat cushion against the backrest horizontally movable. For example, if a lower edge of the back pad substantially
- a structurally simple embodiment of the vehicle seat can be achieved if, the backrest with respect to the vertical direction in a lower region, an upper
- the central region performs a tilting movement at least relative to the lower region. This results in the bulge preferably in the transition region between the central region and the lower region, which is particularly suitable for an advantageous support of the passenger back in the lumbar spine according to a lordosis support position.
- a large bulge can be achieved in a targeted manner in this area, if by implementing the relative movement between the seat cushion and the backrest at least two regions perform a tilting movement, wherein the central region performs the greatest inclination relative to the vertical 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.
- Such a support element causes when occupying the vehicle seat, the bulge can not be pressed by a load by the passenger inward.
- To Need can in the area of the back pad more
- Support elements may be provided, their respective
- the support element can be movably mounted and / or formed by a deformable element, such as, for example, a variable in its length expansion or an inflatable element.
- the selected S-shape allows a particularly favorable adaptation to the contour of the back of a person who uses the vehicle seat.
- the cross section is preferably in a vertical and parallel to the seat direction plane.
- the support elements need not all have an equal degree of mobility, because for example at the top and bottom of the region of the bulge and further away from the bulge, it may be sufficient if the support elements substantially the movement of the
- Figure 1 is a schematic side view of a
- Figure 2 is a schematic representation of the relative
- Figure 3 is a schematic side view of the passenger seat with support elements.
- Figure 1 shows a cross-sectional view of a
- Passenger seat for a large-scale rail vehicle, with a backrest 1 and a seat cushion 2, wherein a
- Lying position B of the passenger seat with solid lines and a sitting position A thereof is shown with dashed lines. Both the backrest 1 and the
- the passenger seat is placed on a vehicle floor F by means not shown and has a seating direction S, which is parallel to the floor F
- Backrest 1 overall on a rather flat contour.
- the backrest 1 in the lying position B can be divided in its vertical direction into three sections la, lb, lc, wherein the sections la, lb and a lower portion of the section lc are to be assigned to a back cushion 4, while the remaining portion of the section lc to the top edge of the backrest 1 a head cushion 5 corresponds.
- middle section lb and the lower portion la in the lying position of the vehicle seat shows a stronger, forward bulge, as is the case in the sitting position.
- the convexity of the back cushion contour takes place in a direction D, which is aligned with respect to the seat direction S to the front.
- This bulge makes it possible, in the sense of a lumbar support, to support a lumbar region of a person using the vehicle seat in the lying position B in a comfortable manner.
- the contour transitions of the vertical sections la and lc in the direction of the central vertical section lb are carried out continuously.
- Sitting position provides the passenger seat in this position a low lumbar support, but is space-saving.
- the backrest 1 in the lying position in cross-section an elongated S-shape, in the lower region of the bulge is present.
- an elongated S-shape of the backrest 1 wherein, however, the bulge of the backrest 4 is much less pronounced.
- a dotted line illustrates the sitting position, wherein the lying position is shown by a solid line.
- An angle illustrates the angle of the
- FIG. 3 which essentially corresponds to the representation of FIG.
- Lying position B change the positions of the
- Support elements 6a, 6b, 6c relative to the frame 3.
- the positions assumed in the sitting position are by means of
- the support elements 6a, 6b, 6c are each a in the illustrated embodiment
- Respective end positions of the support elements 6a, 6b, 6c are designed lockable, so that in particular the present in the lying position B bulge is maintained even under load.
