Definitions
- the invention relates to an unlocking device for a longitudinal seat locking of a vehicle seat.
- the seat frame is generally fastened to upper rails, which are longitudinally adjustable in relation to chassis-side lower rails. Suitable longitudinal positions can be locked or locked by the longitudinal seat lock, so that the longitudinal seat lock is initially unlocked for a subsequent longitudinal adjustment.
- EP 0 878 344 A2 describes a seat longitudinal adjustment in which a pin is provided on the backrest, which abuts on an upper lever arm of a lever mechanism mounted in the backrest axis, wherein a connecting rod is attached to a lower lever arm of the lever mechanism, which in turn its front end is used to operate a WeglCodesentriegelung.
- a connecting rod is attached to a lower lever arm of the lever mechanism, which in turn its front end is used to operate a Weglnaturesentriegelung.
- the lever mechanism is pivoted, which causes the longitudinal seat release via the connecting rod.
- the WeglCodesentriegelung can already be effected by Vorschwenken the backrest.
- DE 102008 008 936 B3 describes a vehicle seat with a longitudinal adjuster for setting a seat longitudinal position. The longitudinal adjuster can be unlocked by means of a handle and automatically locked.
- the longitudinal adjuster can be unlocked even when pivoting the backrest; This unlocking takes place by means of a free-pivoting control element or by means of a fitting provided on a release ring, which is taken during the pivoting of the backrest and then by means of a Bowden cable or the like controls the locking of the longitudinal adjuster.
- the invention is based on the object to provide an unlocking device for a seat longitudinal locking, which can be formed with little effort and allows safe unlocking.
- a release lever is thus actuated by a cable, which is pulled automatically when folding the backrest.
- an active driving means is provided directly to a backrest structural part, so that z. B. an additional, stored lever system is no longer required.
- a driving system is formed, which subsequently allows a driving of the cable when folding the backrest after a first, non-active pivoting angle.
- the backrest can thus first within a first pivoting range, z. B. a comfort tilt swivel range, without this already takes place unlocking the seat longitudinal locking. Only after the backrest has been folded forward beyond this first pivoting area is the cable pulled along, and subsequently unlocked, in that the cable pull actuates an unlocking lever provided on the longitudinal lock.
- the active entrainment means may in particular be a driving hook, which may preferably be attached to the outer circumference of the backrest structure part, in particular in a lower rear region of the outer circumference of the backrest structure part.
- the passive entrainment means is formed in particular with a closed opening, z. B. as eyelet, in particular Langlochinate that is suitably positioned in the pivoting path of the active entrainment means.
- an automatic positioning of the passive entrainment means can advantageously take place so that the rearward locking of the seat longitudinal latch first takes place when the backrest is retracted or folded back, and subsequently the active entrainment means disengages from the passive entrainment means, so that the cable is released.
- the passive entrainment automatically positioned so that it can be taken again in a subsequent folding movement.
- a holding means may be provided, the z. B. on the seat frame or a fitting or Adapter is attached. This holding means may in particular serve both for receiving a rear end of the Bowden cable jacket of the cable as well as for positioning the passive driving means, in particular for securing a suitable rotational position of the passive driving means so that it can be subsequently taken.
- the provision of the cable can be done in particular by a return spring, which returns the release lever in its passive position.
- a return spring which returns the release lever in its passive position.
- the return spring can then relax, so that first the unlocking lever is released again and allows a lock.
- the cable is still taut until it is released from the active entrainment. Even in the normal position when the driving means is not engaged, there may be a basic tension due to the return spring.
- the cable can be connected to the release lever z. B. be connected via a compensation spring.
- This compensating spring can compensate for a given overstroke of the cable pull.
- length tolerances of the cable can be compensated or compensated, so that according to the invention, an adjustment of the cable can be omitted.
- FIG. 1 shows a perspective view of some structural parts of a vehicle seat according to the invention with the unlocking device according to the invention; an enlarged detail of Figure 1 with the seat longitudinal lock in its locked state; the seat lock from another perspective view in the unlocked state; the area of the backrest axle together with inventive driver mechanism for the Bowden cable in un actuated state; the representation of Figure 4 at unlocking by folding the backrest;
- the right backrest side part (backrest structural part, Lehenhoim) 2 of a backrest 3 not shown here are shown in Figure 2.
- the backrest side part 2 or the entire backrest 3 is connected via an adjustment fitting 4 to a seat frame 6 indicated here by dashed lines with its right-hand contour.
- the adjustment fitting 4 allows z.
- the seat frame 6 is attached to upper rails 8, which are longitudinally adjustable relative to the vehicle chassis to be fixed to the lower rails 9 and locked in their longitudinal positions by a longitudinal lock 10.
- the right and left seat longitudinal latch 10 are z. B. coupled together via a torsion bar 12.
- the unlocking of the seat longitudinal locking ment 10 can take place in a manner known per se on the one hand via an actuating lever 13 provided in the front region of the seat frame 6.
- unlocking the longitudinal seat lock 10 via a cable 14 in the easy-entry adjustment of the backrest 3 is possible, as will be explained below.
- An unlocking device 32 has an unlocking lever 16, the cable 14 and a driver system 18 shown in FIGS. 4, 5 for actuating the cable 14.
- the unlocking lever 16 is pivotally mounted on the upper rail 8, wherein this attachment can be made directly or indirectly.
- the cable 14 is guided between the release lever 16 and the driver system 8 as a Bowden cable in a Bowden cable sheath 20 and at its front end 14 a with z.
- the release lever 16 is biased by a return spring 23 in its unactuated initial position and must be operated against the action of the return spring 23.
- the return spring 23 is z. B.
- the Langlocheria 26 attached as inventive entrainment.
- the Langlocheria 26 is positioned in the unactuated position of Figure 4 such that their slot is open to the front.
- the positioning of the Langlocheria 26 can be done automatically by z.
- B. the rear end 14b of the cable 14 projecting from the Bowden cable sheath 20 is sufficiently short and stiff, so that an unambiguous positioning of the long hole eyelet 26 is achieved. gives.
- a holding means 28 may be attached, which ensures a rotationally secure positioning of the elongated eyelet 26 and z.
- B. also the Bowden cable sheath 20 receives.
- a catch hook 30 is mounted, which in the upright position of the backrest 3 and the backrest side part 2 in
- Pivoting direction is positioned in front of the slot eyelet 26. Within the comfort pivoting range of the backrest side part 2 for tilt adjustment, the catch hook 30 does not yet reach the slot eyelet 26.
- the backrest side part 2 can subsequently be folded forwards beyond the comfort pivoting range, as shown in FIGS. 5 and 7.
- this folding movement of the driving hook 30 passes into the slot eyelet 26 and takes them in the further folding movement to the front, so that according to Figure 5 and 7 of the cable 14 is pulled.
- This pulling movement leads according to Figure 3 at the front end 14a of the cable 14 to the fact that the release lever 16 is pivoted against the spring action of the return spring 23, for unlocking the seat longitudinal lock 10th
- the slot eyelet 26 thus remains in its inoperative rest position shown in FIG. 4, so that the catch hook 30 passes downwards and forwards from the slot eyelet 26 during its further pivoting movement, until the position of FIG. 4 is reached again.
- the unlocking device 32 thus comprises in this embodiment the unlocking lever 16, the Bowden cable 14, 20 and the driving system 18, which includes the elongated eyelet 26 and the driving hook 30.
