Description

. The invention relates to an adjustable seat mount for a vehicle seat, and one object of the invention "is to provide an improved attachment, which withstands greater stresses without being torn off are manufactured, however, at a relatively low cost .can be.

According to one feature of the invention, the seat attachment includes a message G- o.c * er release lever in Jona one bar extending in the transverse direction,

This crossbar can be located below the seat and in front of « train or stretch below the front rope of the sit se θ a, and it is much easier to operate than a Handle or knob on a soite of the seat or uater the front part of which is arranged so that the user is nasty Must search for the handle or button by hand. DiQ Crossbar should be easy to find, and it can be attached to a; any. Point ssvdochon their endon be grasped in order to

to be made.

Usually 1st dio quorotange with a release device the fastening device on one side of the seat and possibly with similar AuolÖBevorrichtungen on iwei Fastening devices connected, of which each oine on Each side of the seat is arranged *

• In a preferred embodiment of the invention the crossbar through the connecting portion of a component formed with a strongly flattened U-profile, the legs of which extend backwards to the rear opening devices on both. Sides of the seat extend »The release mechanism can close be provided for the purpose, an adjustment of the seat near the front or back or an adjustment of the seat upwards or below to enable.

According to a second feature of the invention, which relates to the high load-bearing capacity of the fastening device, a slide is provided for a vehicle seat which can be moved in the direction of travel and which comprises U-shaped profiles that can be moved relative to one another and at least one should come into effect between the two profiles ; this Bo-lle _τ is elastically deformable so that the U-sections can touch over a substantial part of their length when they are subjected to a load which substantially exceeds the weight of a passenger.

da3 For this purpose it is possible 'to move the roll or two lengthways

the sliding U-profiles arranged at a distance from each other Hollen or * four Hollen that make up a complete

a seat holder with two / one sleds, of which / on each Side of the seat is arranged, designed and arranged that their deformation is initially called an increase the load increases rapidly, and that afterwards the deformation increases more slowly. For this purpose you can get a massive one i'ell the roll one or more hollow sections of assign larger diameter; for example, the hollow sections could be formed by flanges that are on both Rarely are a massive middle grain section arranged »

Normal deformation under the effect of weight ednos passenger does not allow the U-profiles to come into contact with the above to come together so that you sit on the seat- ' de passenger can easily adjust the seat in the direction of travel, and that it is possible that the seat on the 'only slightly deformed holloa in the U-profiles. runs.

Of course, locking means are also provided which are used for .. Effect brought \? Ground as soon as the seat with respect to the longitudinal -'- · ■ "■ aohse of the vehicle has been brought into the desired position. is.

_x ::. "- 'However, if very high stresses occur, such as can happen in a collision, the roller can be deformed to such an extent that' the U-profiles are brought into contact with one another so that they work together and deform together as a carrier in order to withstand the stresses and to prevent the seat from tearing off the fastening device.

Did invention also sees a role for such Fastening device before that oo is designed that they sioh deformed in a predetermined way during bolaoting.

Further details and advantages of the invention _t fare.

i see from the following description of an example embodiment

on the basis of the drawings *

Fig. 2 shows the arrangement according to Fig * 1 in a larger Scale in a front view.

Figo 3 shows on an even larger scale one of the Sleds used ßolle auüü Hylon.

The Sitzschlittenbaugruppo comprises "in inneree or lower" U-profile 11 and an outer bcw. Upper U-profile 12 which both have an elongated shape, and with which $ o two sonkrecht arranged screws or threaded bolts IJ are welded, making it possible , the slide construction both Λ "and solidify at the bottom of a vehicle to a seat frame to loading% It should be noted that s.ind provided'baugruppen sled at two spring seat, each of which arranged one on each side] of the seat and extends in the direction of travel; thus the user of the seat can change the position of the seat in the direction of travel »

The Ü-profiles 11 and 12 are normally out of contact held together by rollers 14 · made of Hylon; , each assembly is assigned two such roles;

if the seat is to be adjusted, the castors roll 14 along the "relevant assembly in a guide that goes through the collaborators. U-shaped ropes 15 "and 16 of the two U-profile is formed.

Laterally beyond the U-shaped section 15 are the; Side walls of the inner U-profile to the outside and below angled so that they are gomaS Fiß »2 vertical flanges 1? form, which connect to öino school gate 18. "

which is bent like a normal eraser. One Load of the size mentioned is therefore not only applied locally, as is the case with a ball or roller made of steel but the load is distributed over a large part of the U-profile, and therefore is for sufficient strength ensured j so that the seat is not torn off the fastening device; boi the construction according to the invention you do not need more material for the production of the fastening device than "bsi fastening devices of the known type.

The position in the longitudinal direction is determined by a determined pivotable lever Jl, which carries a locking member 32, which each engage in one of several cutouts 33 of the flange 17 below the normal axis of the profile kannj d.lu in a component that does not serve the purpose of Art a support of a deformation of the U-profile a resistance to oppose.

U-profile 12 are connected. After attaching the lever, Sichorun ^ s discs 36 are pushed onto the Kietcn; This gives you a cheap and easy-to-assemble fastening ^{device "According to I r} igo 1, the linko Nioto 34 acts as a bearing pin for the lever 311 while the rochto lliote works together with a slot 35 in the lever" to form an anchoring; In other words, the latching member 32 can still be in or out of engagement with the relevant eye

The slide assembly is on "both. Sides with each." provided such a lever 51, -and these levers can operated simultaneously with the help of a crossbar "extending in the transverse direction below the front part of the seat extends and at "both ends one backwards extending tubular arm 37, the daa end 38 of the "relevant lever 31 receives,"

A wire spring 39 that comes into effect between the U-profile 11 and the arm 37 _? spans the crossbar in a counterclockwise direction as shown in FIG. the left rivet 34- around into that position "in which the locking elements 32 engage in the" relevant cutouts 35. In addition, the spring de serves to hold the arm 57 on the associated end 38 of the lever 31 in that it engages in notches on the top serving two parts. A ramp 41 is' at the rear end of the arm 3? designed so that the spring 39 is automatically lifted upwards when the arm ^{f is} pushed over the end of the lever until the spring engages in the notches. Thus, the parts of the device can be assembled quickly.

On each side of each inner U-profile II, at a point which is separated by a distance from the end of the movement in the longitudinal direction, a nylon-shaped slide guide 43 is provided, which carries an extension, wolcheff into the last recess 33 nm End of row engages; Forner, each carriage guide 43 carries two arms, which cynically don toGammen attached to the side parts of the U-profile 11 and are arranged u & 4 on the upper surface of the U-profile
