Definitions
- the invention relates to a vehicle seat according to the features of the preamble of claim 1.
- Such a vehicle seat is known from DE 199 49 728 AI.
- the vehicle seat shown there is slidably mounted in a vehicle via rails. It has a drag that is guided in a guide.
- the vehicle seat should be able to be securely connected to the vehicle structure.
- the vehicle seat has a releasable locking device, which is used to hold the dragrest in one Backdrop guide is formed.
- the locking device can be operated manually, ie locked or unlocked. When the locking device is unlocked, the dragrest can simply be installed in a vehicle and fastened there by actuating the locking device. Also a simple removal of the vehicle seat, e.g. B. maintenance or repair work is possible. For this purpose, the locking device of the backrest is released manually, whereupon the seat, preferably the backrest, can be easily removed from the vehicle.
- the dragrest is guided in a link guide which is connected to the vehicle structure and has two link tracks.
- a slide track is provided on each side of the drag back.
- the locking device of the backrest engages in the slide tracks with two bolts and thus connects the backrest to the vehicle structure.
- the backrest is thus firmly and securely anchored or held in the slide tracks on both sides via the bolts of the locking device and at the same time guided displaceably.
- the drag back has a tube that runs transversely to the drag back and supports the bolts of the locking device.
- the tube is preferably designed to be continuous over the width of the drag back and connected to a supporting structure of the drag back, preferably the frame of the drag back.
- the bolts of the locking device can be mounted axially displaceably in the tube.
- the bolts can be axially displaced by means of a manually operable tension band or a chain that interacts with the bolts, and thus for anchoring the dragrest in engagement with the link tracks and / or for releasing the The backrest can be disengaged from the slide tracks.
- the tension band and / or the chain is designed to indicate the correct locking position of the drag back.
- the chain and / or the drawstring can have a marking which, when the bolts are locked, coincides with a marking which is fixedly arranged on the vehicle seat. If the vehicle seat or the backrest has not been locked correctly, the bolts cannot be extended to their end position via the drawstring and / or the chain and the marking on the chain and / or the drawstring does not coincide with the marking on the seat ,
- the marking of the drawstring is designed as a hook and / or eyelet and / or tab.
- the marking which is fixedly arranged on the vehicle seat is accordingly designed as a pin and / or hook, so that when the towing arm is correctly locked, the drawstring and / or the chain can be attached to the seat by connecting the markings, and can preferably be fixed.
- vehicle seat according to the invention it is possible to use the vehicle seat according to the invention in passenger cars, buses, as well as water or rail vehicles. Use of the vehicle seat according to the invention as a comfortable passenger armchair in aircraft is also provided.

- FIG. 2 a representation of the opened locking device
- FIG. 3 an illustration of the locked locking device
- FIG. 4 a perspective view of the locked locking device
- FIG. 5 an enlarged representation of the bolt of the locking device
- Figure 6 a representation of the suspension of the drawstring in
- FIG. 7 an illustration of the attachment of the drawstring in the vehicle seat below
- FIG. 1 shows a vehicle seat 1 with a drag back 2 and a seat cushion 11.
- the vehicle seat 1 is slidably mounted on rails 12 in a vehicle.
- the contour of the upholstery of the backrest and seat cushion is indicated with hatching.
- the backrest 2 has a cushion-bearing backrest frame 21 and is slidably mounted in a slide guide 22 fastened in the vehicle with slide tracks 23.
- the backrest 2 is pivotally and easily detachably connected to the seat cushion or the rails 12, e.g. B. hung or inserted.
- the height and the inclination of the backrest 2 are changed by adjusting the seat cushion 11.
- the seated person can thus freely choose and / or adjust his sitting position between a more upright sitting position and a more inclined resting position.
- the backrest 2 is detachably connected to the link guide 22 fixed to the vehicle.
- the locking device is arranged approximately halfway up the backrest 2 and is constructed symmetrically. It comprises a cross tube 31 and two bolts 34 engaging in the link tracks 23 arranged on the left and right of the backrest 2, and a central tension band 33, which is connected to the bolts 34 via lever 32.
- the cross tube 31 extends transversely to the backrest 2 and is firmly connected to the backrest frame 21. It supports the two bolts 34 in an axially displaceable manner in an elongated hole, the bolts 34 being displaceable beyond the open ends of the cross tube 31.
- the backrest frame 21 has two legs connected to one another on its one end side, so that the cross section of the backrest frame is approximately U-shaped.
- the link guide 22 engages in the space between the two legs of the backrest frame 21 at the level of the cross tube 31 on both sides of the backrest.
- the inner leg of the backrest frame 21 is connected to the cross tube 31 and has an opening through which the bolt 34 can reach.
- the opening of the slide track 23 and an opening in the second leg of the support frame 21 are arranged.
- the bolt 34 arranged on both sides of the backrest 2 engages through the link path 23 and engages behind the opening in the outer leg of the backrest frame 21.
- the locking device 3 thus holds the backrest 2 firmly in place Vehicle.
- the bolts 34 are completely retracted into the cross tube 31 and out of engagement with the link tracks 23, so that the backrest 2 can be easily removed from the vehicle.
- the two levers 32 are each rotatably connected at one end to a bolt 34. At their other end, the levers 32 are rotatable with one another and connected to the tension band 33.
- the drawstring runs behind the vehicle seat 1 and is accessible from above on the top of the backrest 2 and from below on the seat cushion 11. It can be operated manually.
- To lock the drawstring 33 is pulled down, whereby the bolts 34 are moved outwards via the lever 32.
- a stop 35 limits the path of the drawstring 33 downwards. It is arranged so that in the locked position the levers 32 are at a flat angle to one another beyond the center position of exactly 180 °. This compensates for any play in the locking device 3 and achieves a stable locking position.
- When unlocking the drawstring 33 is pulled up.
- the bolts 34 are moved inwards via the levers 32 and release the drag back 2.
- the locking of the backrest 2 can be checked via the path of the drawstring 33. If the drag back is locked correctly, the tension band 33 is pulled down from the position shown in FIG. 2 to the position shown in FIGS. 3 and 4. If, for example, the backrest 2 is not correctly positioned or one of the openings cannot be reached through freely, the levers 32 can not be operated up to the locking end position. The distance traveled by the drawstring is therefore less.
- the tension band 33 has a tab 36 which is arranged on the tension band at such a dimensioned position that it can only be hooked into a pin 37 arranged on the seat frame 21 when the dragrest 12 is locked correctly. This marking in the form of the tab 36 allows the correct locking of the backrest 2 to be checked in cooperation with the pin 37 despite the locking device 3 not being visible.
- the drawstring 33 is secured on the pin 37 against slipping.
- the pin 37 has a locking nut 38 which prevents the tension band 33 from being released unintentionally.
- the lock nut 38 is screwed onto the pin 37 after the drawstring 33 has been hung in, so that the drawstring 33 cannot unintentionally detach from the pin 37.
