Description

The invention relates to a Lehnenentriegelungseinrichtung for a vehicle seat and a vehicle seat with such Lehnenentriegelungseinrichtung.

Such Lehnenentriegelungseinrichtung is from the DE 199 28 114 C1 known. The backrest with its backrest frame is tilt-adjustable with respect to a seat frame of the vehicle seat and can be locked in different inclinations by a backrest lock fitting (recliner). The backrest lock fitting generally has a lower fitting part for attachment to the seat frame and a fitting upper part for attachment to the back frame, wherein the two fitting parts can be locked by a recliner heart, which can be unlocked via a Lehnenentriegelungseinrichtung.

The seat occupant actuates a release lever for unlocking the backrest lock to subsequently adjust the backrest and lock in the new backrest tilt. The release lever is generally placed on an unlocking shaft, which is positively received in the backrest lock. According to the DE 199 28 114 C1 In this case, a lock washer is formed with integrally formed, radially inwardly directed spring tabs and a circumferential closed edge of the disk body. The spring clips are used for clamping, rotation-rigid contact with the outer surface of a square-shaped unlocking shaft. By spring tabs an axial securing on the unlocking shaft is still possible. Such a locking washer can be integrally formed from a metal plate and in particular also facilitates assembly, as it serves for the axial securing of other components.

The DE 10 2013 112 763 A1 describes a backrest tilt adjustment with two internally toothed flanges, are inserted into the pawls, which are adjustable between a locking position and an unlocked position.

Such training is relatively expensive; Furthermore, the assembly with a variety of components is quite complex.

The backrest lock is generally designed to ensure crash safety of the backrest against front and rear crashes. However, it can also be more overloads z. B. occur due to improper use, in which the vehicle seat or parts of the Lehnenentriegelungseinrichtung be excessively burdened by a user.

The DE 10 2011 122 435 A1 shows a mounting arrangement of an operating lever for a locking fitting of a vehicle seat. Here, the operating lever made of plastic and is arranged in front of a plastic, mounted on the vehicle seat cover and connected to release or locking the locking fittings torque transmitting with a standing in operative connection with the locking fittings shaft.

The DE 10 2014 207 363 A1 shows a Lehnenversteller for a vehicle seat with at least a fitting upper part, a fitting base and a fitting arranged therebetween. Furthermore, an adapter is provided, which is fixed by a recess in the fitting upper part or lower fitting part on the fitting.

The DE 10 2013 210 688 A1 shows a fitting system for a vehicle seat with two fittings that are locked with each other and rotatable relative to each other about an axis. To unlock the fitting, a transmission device is provided, which is rotated by a hand lever, wherein on the fitting rotatable about the axis of a stop module is mounted, which is in operative connection with the hand lever and the transmission rod.

The invention has for its object to provide a Lehnenentriegelungseinrichtung and a vehicle seat with such Lehnenentriegelungseinrichtung that allow easy and safe installation with little effort and high comfort.

This object is achieved by a Lehnenentriegelungseinrichtung according to claim 1. The dependent claims describe preferred developments.

Thus, a securing clip is provided, which couples to a torsionally rigid with both the Entriegelungswelle and the Lehnenentriegelungshebel, and further allows an axial securing on the Entriegelungswelle by suitable fixing means.

In which the fuse clip directly receives the Lehnenentriegelungshebel and axially coupled with him, a secure connection and axial securing of Lehnenentriegelungshebels and the entire arrangement of backrest lock (Recliner), Entriegelungswelle and Lehnenentriegelungshebel can be achieved. The backup clip can z. B. initially be secured on the Lehnenentriegelungshebel by clipping or plugging. The securing clip is attached in the axial direction (longitudinal direction) on the unlocking shaft and allows axial securing by fixing, so that With little effort and few assembly steps, both axially and rotationally fixed and secure arrangement is formed.

The fixing of the securing clips for axial or longitudinal fixation on the unlocking shaft can in particular by clamping action, for. B. in the Entriegelungswelle engaging clamping lugs (in particular for securing) in the insertion (forward) and further by tilting a backward (axially outward) bent tab. Thus, such a fixation by clamping with little effort is possible, namely by only suitable shaping by punching out of the fuse clips and bending appropriate areas. For this purpose, the securing clip is preferably formed from a hard spring steel, which can thus engage in the possibly formed of softer steel unlocking shaft.

The Lehnenentriegelungshebel is thus preferably secured axially by a positive connection with the securing clip and thus attached to a captive; Furthermore, a rotation-rigid coupling to the securing clip is made possible, so that the Lehnenentriegelungshebel z. B. completely formed of a plastic material and can be plugged with a suitable receiving hole or receiving area on the Entriegelungswelle, then a rotationally rigid coupling and securing in the direction of rotation can be done via the fuse clip; so the axial securing between the Lehnenentriegelungshebel and the securing clip in the radial direction spaced from the axis of rotation and thus take place with a larger lever arm, z. B. by snap-hook (snap hook), which engage and snap into windows of the fuse clips axially; Thus, an axially secure and continue to ensure the rotationally rigid coupling Lehnenentriegelungshebels on the Entriegelungswelle.

Furthermore, the torsionally rigid receiving the Entriegelungswelle in the backrest lock (Recliner) involving the backup clips done by the resting on the Entriegelungswelle receiving finger of the securing clips are received in the receiving hole in the backrest lock and thus the receiving hole is slightly larger than the outer shape of the unlocking shaft dimensioned , As a result, a firm connection of the securing clips and thus the Lehnenentriegelungshebels is made possible on the backrest lock.

Another advantage of the invention lies in the formation of an overload protection against an abusive pivoting operation. For this purpose, the Lehnenentriegelungshebel formed of a plastic material on a torsionally soft area on which a comfort stop is designed to rest on a first Reclineranschlag. In the locked, unactuated basic position of the Lehnenentriegelungshebel is thus with its plastic material on the metal of the first Reclineranschlags and is preferably pressed by the spring bias of the Recliners to this Reclineranschlag, creating a secure investment without rattling or other metallic noise is achieved.

Furthermore, an overload stop is formed on the metallic safety clip, which upon torsion of the torsionally soft region, d. H. a relative rotation of the Lehnenentriegelungshebels over the rigid assembly of unlocking shaft and securing clip, comes to rest on a second Reclineranschlag; This Recliner stop can also be the first, or a second recliner stop.

Thus, if a user exerts an overload on the Lehnenentriegelungshebel, z. B. rises with his foot on the Lehnenentriegelungshebel to load the roof of the vehicle or the like, the Lehnenentriegelungshebel in his torsionally soft area give something, so that subsequently a security stop or overload stop the metallic security clips against the backrest lock or a lean lock-resistant part passes, whereby a secure overload function is realized. Thus, both a comfort stop of the plastic material of Lehnenentriegelungshebels and in such overload cases, a safety stop or overload stop of metal to metal can be achieved with torsionally rigid coupling.

The training with clip-on safety clip and latching Lehnenentriegelungshebel a simple assembly effort at low production costs is possible, with easy-to-form components can be used, for. B. a trained as a plastic injection molded part unlocking lever and a made of a sheet metal washer securing clip.

The torsionally soft area of Lehnenentriegelungshebels z. B. have an axially extending collar and / or radially extending struts, which can be integrally formed with other areas of Lehnenentriegelungshebels from the plastic material.

The safety clip is preferably provided with further features for functional improvement. So the fuse clip z. B. with a base plate and from the base plate to the front (for backrest locking out) bent tabs are formed at which bearing fingers are formed to rest on the Entriegelungswelle. Thus, a higher stiffness is achieved by partial Two-layered allows, for. B. with bent tabs and interlocking braces by bent tabs, which leads with production engineering little effort to a significant increase in strength and higher rigidity against rotational loads.

The axial fixation of the securing clips on the unlocking shaft can be achieved, for example, by a z. B. in the area of the base plate provided clamping edge or contact edge axially to the rear, and formed by the front tabs fixed fingers axially forward, so that the fuse clip jammed on the Entriegelungswelle or digs.

The connection of the securing clips Lehnenentriegelungshebel can by positive snap snapping projections of Lehnenentriegelungshebels in z. B. windows of the fuse clips and by a frontal attachment.

Thus, a vehicle seat with back frame, seat frame, backrest lock and such Lehnenentriegelungseinrichtung of securing clip, Entriegelungswelle and Lehnenentriegelungshebel is created, which allows high security, ease of design and high comfort.

From a vehicle seat 1 is in z. B. 2 a backrest frame 2 a backrest which is pivotable relative to a seat frame of a seat part and lockable in its pivoting positions. For this purpose, a Lehnenverriegelungs fitting (recliner) 3 provided, with its lower fitting part 4 on the seat frame and with its upper fitting part 5 on the backrest frame 2 is attached. Between the seat frame-fixed fitting base 4 and the reclining frame-fixed fitting shell 5 is a backrest lock (recliner heart) 6 provided from the sectional view of the 2 can be seen and by a Lehnenentriegelungseinrichtung 7 can be unlocked, in turn, a Lehnenentriegelungshebel (operating lever) 8th made of plastic, designed as a square unlocking shaft 10 and a backup clip 12 having.

The backup clip 12 is made of metal, in particular a spring steel, and advantageously formed from a stamped, curved disc. The backup clip 12 and the backrest release lever 8th are positively on the square outer shape of the Entriegelungswelle 10 attached, which also continues the backrest lock 6 receives; this is indicated by the backrest lock 6 a square, in particular square through hole 6a on, leaving the unlocking shaft 10 can be pushed through; the unlocking shaft 10 can in particular extend in the transverse direction through the entire backrest, wherein z. B. on the left and right side in each case a backrest lock 6 is provided, which together by the Entriegelungswelle 10 be unlocked. The backrest lock 6 is spring biased to the latched position, allowing the user to pivot by pivoting the backrest release lever 8th against this preload the backrest lock 6 unlocked to subsequently adjust the backrest in its inclination, z. B. against a spring preload of the backrest.

The backrest release lever 8th is z. B. as single-shell plastic part, z. B. plastic injection molded part and has a central, inwardly (towards the interior of the seat) projecting collar 14 with radially inwardly projecting towards the axis A out webs 15 on, which - such. B. from the section of 3 visible - a wave receiving area 16 for positive and frictional recording of Entriegelungswelle 10 support; Here are other training for positive and frictional recording of Entriegelungswelle 10 possible. The backup clip 12 is - as in particular from the exploded view of 8th of the second embodiment - also in the first embodiment with its receiving hole 12a on the unlocking shaft 10 inserted and here between the Lehnenverriegelungsbeschlag 3 and the backrest release lever 8th intended. The backup clip 12 has clamping means for clamping axial securing on the unlocking 10 on how out of the cut the 5 can be seen in more detail, wherein in this sectional view, the sectional area of the securing clip 5 hatched for clarity: The fuse clip 12 has forward-looking receiving fingers 12b , z. B. according to the embodiment of the 1 to 5 two recording fingers 12b on, thus between them the unlocking shaft 10 take up, with the receiving finger 12b flat on opposite sides of the unlocking shaft 10 rest and at least forwards front fixing (clamping means) 17 train, here as locking lugs 17 into the (softer) material of the unlocking shaft 10 are pressed, this representation in 5 for clarity a little bit oversubscribed. Because the backup clip 12 is formed of hard spring steel, according to such latching a detent 17 in the metal of the unlocking shaft 10 possible.

To the rear, a clamping effect z. B. according to 5 through a clamping edge 18 a tilted sheet edge of the base plate, the receiving hole 12a of the backup clip 12 defined to be formed, this clamping edge 18 corresponding obliquely backwards and inwards, so that the clamping edge 18 against a shift of the security clip 12 to the outside (in 5 to the right) secures. Furthermore, the backup clip 12 advantageously by suitable stops in the backrest lock 6 secured in the axial direction, according to 5 through a stop nose 19 as a rear end of a back and up elastically bent stop finger 20 ,

How out 5 Furthermore, it can be seen, the fuse clip 12 be stiffened by suitable shaping, in which case z. B. a reinforcing bar (reinforcing finger) 22 is bent over and thus bent plate portions of the fuse clips 12 locked together; Such locks and stiffeners by beads etc. increase the rigidity of the made of a single sheet metal plate (spring steel plate) securing clips 12 ,

As in 5 shown, the through hole 6a the backrest lock 6 be dimensioned slightly larger, so that only by inserting the backup clip 12 with its recording fingers 12b the positive reception of the unlocking shaft 10 he follows; however, for example, the backup clip may still be used 12 not completely in the axial direction in the through hole 6a be plugged so that a rear (in 5 thus left) area of the backrest lock 6 directly form-fitting the unlocking shaft 10 receives.

The backup clip 12 will continue in the collar 14 and its other form-fitting form of the Lehnenentriegelungshebel 8th recorded, in particular from 1 and 2 it can be seen: This is how the fuse clip points 12 z. Eg windows 12c on, through the protrusions 14a of the collar 14 protrude in the axial direction, thereby already a fixation in the circumferential direction or for torque transmission is formed. For this purpose, the backup clip 12 corresponding bent attachment tabs 12f for lateral contact with the projections 14a exhibit. Furthermore, the collar snaps 14 in locking lugs 23 in an outer edge 12g of the backup clip 12 and thus engages behind this, to secure the recording clips 12 in the axial direction forward (in 1 to the left). Furthermore lies the security clip 12 - z. B. in the outer edge 12g - frontally on the collar 14 on, for securing and receiving axially outward (in 1 to the right).

Thus, the backup clip 12 with the backrest release lever 8th both firmly connected in the axial direction to both directions, as well as in the direction of rotation towards both directions of rotation, so that the Lehnenentriegelungshebel 8th with the backup clip 12 and the unlocking shaft 10 form a rotation-rigid unit.

• - zunächst der Aufnahmeclip 12 auf die Entriegelungswelle 10 gesetzt werden,

dann diese Anordnung in den Recliner bzw. die Lehnenverriegelung 6 gesetzt werden,
dann der Lehnenentriegelungshebel 8 aufgesetzt werden.In particular, during assembly

• - First, the recording clip 12 on the unlocking shaft 10 be set

then this arrangement in the recliner or the backrest lock 6 be set
then the backrest release lever 8th be put on.

But there are also other montages possible.

The backrest unlocking device 7 is according to 3 in the locked basic position, ie at unopposed Lehnenentriegelungshebel 8th , with a comfort stop (soft stop) 32 made of plastic Lehnenentriegelungshebels 8th at a first recliner stop 27 of the seat frame-fixed fitting lower part 4 at. The recliner stop 27 can in particular - as well as in the embodiment of 7 can be seen formed on a bent, extending in the axial direction metal tab. The comfort stop (soft stop) 32 is at the torsionally soft area 14 . 15 ie the collar 14 or in particular according to 3 on a strut 15 formed and thus in accordance with the elasticity of this construction and the plastic material in the direction of rotation elastically yielding. By the soft contact with the plastic material thus occurs no rattling sound or the like, wherein the spring bias of the backrest lock (recliner heart) 6, the Entriegelungswelle 10 together with security clip 12 and Lehnenentriegelungshebel pulls into the normal position, ie the comfort stop 32 to the seat frame fixed recliner stop 27 suppressed.

Excessive load on the backrest release lever 8th , In particular, a torque acting counter to the operating direction down on the Lehnenentriegelungshebel, there is initially the risk of damage to the plastic material on the comfort stop 32 , The rotation-soft area 14 . 15 However, allows elastic, non-destructive compliance against such overload torques, which in particular by structuring with collar 14 and jetties 15 as well as the elastic plastic material is made possible. Due to this flexibility, the unlocking device thus rotates in this overload case 7 continue until an overload stop (hard stop) 33 of the backup clip 12 against the recliner stop 27 arrives. This overload contact can also be at another point of the Recliner attack 27 done, z. B. slightly offset in the axial direction of the metal tab of the seat frame fixed fitting base 4 so that a first and second Recliner stop may possibly be different.

Thus, under a heavy load or in case of overload, a firm investment of the metal of the security clip 12 , which is rigid on the unlocking shaft 14 is seated at the metallic recliner stop 27 of the seat frame-fixed fitting lower part 4 of the backrest fitting 3 ensured. Here are the recliner stop 27 as well as the attacks 32 . 33 spaced from the axis A in the radial direction to form a suitable lever arm.

Thus, the backup clip allows 12 due to its shape and its installation a rotationally rigid coupling of Lehnenentriegelungshebels 8th to the unlocking shaft 10 and the unlocking 6 , wherein additionally a comfort stop and overload stop are formed.

In the embodiment of the 6 and 7 is merely a different shape of Lehnenentriegelungshebels 8th shown here with a collar 14 with several collar areas, z. B. in threefold training, wave recording in the field 16 , wherein the collar areas of the collar 14 again an engagement on the security clip 12 enable. The backup clip 12 is provided here in a similar construction as in the first embodiment.

This is where the backup clip points 12 advantageously non-moving side flaps, in particular in 1 can be seen at which then the forward projecting finger 12b are formed (yet reference numerals for these two tabs.)
