Definitions

  • the invention relates to an adjustable vehicle seat.
  • Such seats consist of a frame with a seat cushion, a backrest articulated on the frame of the seat cushion and an adjustable headrest.
  • the backrest can be varied in its angle of inclination via an adjustment mechanism.
  • Such seats usually have a backrest with a swivel mechanism, particularly in two-door vehicles, in order to allow passengers to get in and out of the rear seats.
  • the swiveling mechanism is locked in the seating position of the backrest by a lock and can be unlocked for swiveling the backrest forward.
  • Form the swivel mechanism and the adjustment mechanism either one unit or consist of two separate devices, with the catch either on the backrest or on the seat frame.
  • the backrest is attached to the seat frame.
  • the vehicle seat is connected to the vehicle floor by means of two rails which can be moved relative to one another. Accordingly, the user can adjust the sitting position in the horizontal longitudinal direction of his leg length.
  • the height adjustability of the seat allows the seat to be adapted to the body size of the user, in particular the seat height can be adjusted to the optimum position for operational safety and driver comfort.
  • a known mechanism for adjusting the seat height uses two lever arms, by means of which the seat frame is stably connected to the upper seat rail.
  • the seat height is set, for example, via an adjustment mechanism which is located between one of the lever arms and the frame or the rail. When the lever arms are in a vertical position, the seat is in its highest position.
  • the backrest Since the backrest is attached to the frame of the seat in all known devices for adjusting the seat height, it is inevitably moved with the seat frame and changes its height position when the seat height is adjusted. The seat frame or the height of the seat cushion can therefore not be changed independently of the backrest in known vehicle seats.
  • the headrest must also be adjustable in order to ensure adjustment not only of the seat height but also of the distance between the seat cushion or frame and the headrest.
  • the seat height for example in the case of a tall person, not only the seat cushion with the frame must be adjusted, but also the headrest must be extended in order to be able to catch the back of the head in the event of an impact.
  • the seated position of the user can be increased in known seats, but the excessive distance between the seat cushion and headrest remains unchanged. An adaptation of the back or the head to the backrest and the headrest is thus excluded.
  • the backrest swivels forward enough space for boarding in the upper area of the boarding, but when boarding the unchanged position of the seat frame leads to a hindrance to the passenger in the foot area.
  • the small space between the seat frame and the door frame is often neither for the passengers are still sufficient to load the rear vehicle seats with bulky objects. This problem is exacerbated when the driver or user of the front seat has set the seat to the rear maximum position due to its body size.
  • the invention is based on the problem of creating a vehicle seat which avoids the aforementioned disadvantages of known vehicle seats and can be better adapted to the requirements of the user.
  • the solution to the problem is based on the principle of attaching the backrest and the seat frame or the seat cushion to the vehicle or to the longitudinal rail independently of one another.
  • a vehicle seat with a displaceably mounted longitudinal rail to which a seat cushion and a backrest are articulated.
  • the seat frame is preferably connected directly to the upper longitudinal rail and via a swivel joint to the lower region of the backrest directly or via a lower frame.
  • the pivot point of this swivel rotates when the backrest is swung forward around the articulation between the upper longitudinal rail and backrest.
  • the seat frame is moved forward when the backrest is swung forward. This creates additional space for the passenger in the foot area ("Easy Entry").
  • the swivel joint between the seat frame and the backrest can have a further degree of freedom within the lower region of the backrest, for example by being axially displaceable within a groove. In this way, especially in the case of height-adjustable seat frames, a problem-free interaction between the backrest and seat frame is achieved when the backrest is swung forward.
  • the seat cushion can be adjusted in height independently of the backrest with the aid of the invention. This also makes it unnecessary to adjust the headrest. This can thus be integrated into the backrest and, after adjusting the seat frame height, is always in the optimal position for the user.
  • this swivel connection can be connected to an adjustment mechanism for the height position of the seat frame.
  • Fig. 1 shows a vehicle seat according to the invention 2 shows the height adjustment mechanism of the vehicle seat of FIG. 1,
  • Fig. 3 shows a cross section through the adjustment mechanism of Fig. 2
  • FIG. 4 shows an unlocking lever of the adjusting mechanism of FIG. 3.
  • the vehicle seat 1 consists of a seat frame 2 with a seat cushion 3 and a backrest 4.
  • the seat frame 2 is connected to an upper longitudinal rail 7 by means of two lever arms 5, 6.
  • the backrest 4 is articulated on the upper longitudinal rail 7, which is slidably mounted on a lower longitudinal rail 8.
  • the seat frame 2 is connected to the connecting piece of the lower region of the backrest 4 via a swivel joint 11 which vertically engages in a guide slot 9.
  • a hook 12 is also rotatably mounted about a bolt 13 and, in its locked position, engages around a bolt 14 fastened to the upper longitudinal rail 7.
  • the hook 12 holds the backrest 4 in the locked position and is unlocked before the backrest is pivoted forward.
  • the backrest can then pivot freely about a bolt 15.
  • the seat frame with the seat cushion can assume different height positions.
  • the lever arms 5, 6 are connected via bolts 15, 16, 17, 18 to the upper longitudinal rail on the one hand and to the seat frame on the other. Due to the non-positive connection with the connecting piece of the lower region of the backrest 4, the forward pivoting movement of the backrest is transmitted to the seat frame 2 and the seat cushion 3, whereby these likewise move forward by pivoting about the bolts 15, 16, 17, 18.
  • the swivel joint 11 connects the seat frame 2 and the connecting piece of the lower region of the backrest 4 via an adjustment mechanism 19 with which the height position of the seat frame 2 or the seat cushion 3 can be adjusted.
  • the adjustment mechanism 19 consists of a pinion 21 at the end of the swivel joint 11, which engages in a toothed rail 22 which is firmly connected to the connecting piece of the lower region of the backrest 4.
  • the swivel joint 11 consists of a spar 23 which is mounted between the right and left connecting piece of the lower region of the backrest 4 m, two eyelets 24 fastened to the right and left of the seat frame 2 and on which a torque is provided by means of a torsion spring 10 to support the upward movement the seat frame 2 is exercised.
  • the height of the seat frame can be adjusted by means of a wheel attached to the spar 23.
  • the end of the spar 23, which is designed as a groove, moves in Guide slot 9.
  • the pinion is locked by means of a locking rail 25.
  • the locking rail 25 is operated with the aid of a hand lever 26.
  • the hand lever 26 is mounted on the connecting piece of the lower region of the backrest 4 via bolts and bearing eye B.
  • Two fingers 27, 28 engaging in the hand lever are pressed apart by a spring 29 and thus pressed against the inner surface of the hand lever forming a cavity.
  • Two pins 33, 34 connected by a bridge 32 are located at the level of the locking rail. The pin 33 engages in an opening in the locking rail 25, while the pin 34 is connected to the hand lever 26.
  • the spring 29 guides the hand lever back into its starting position when the load is released.
  • the invention offers advantageous application options for a wide variety of vehicle types, in particular if space and / or adjustment problems are to be solved.
