Definitions
- the invention relates to a locking device for a motor vehicle seat adjustable along an adjustment direction according to the preamble of claim 1 and a longitudinal rail guide herewith according to the preamble of claim 19.
- the motor vehicle seat should be adjustable along an adjustment direction does not mean that the seat as a whole must be adjustable. Rather, this should also include the adjustability of individual seat components along an adjustment direction. A respective adjustment position of the corresponding seat components can be locked using the locking device.
- Such a locking device comprises a locking rail (extending along the adjustment direction) which has a plurality of locking openings arranged one behind the other and spaced apart from one another along the adjustment direction, as well as a locking unit which is movable along the adjustment direction relative to the locking rail and which has a plurality of locking elements which are guided independently of one another by means of a guide device and which can be brought into engagement with a locking opening of the locking rail independently of one another (along a locking direction) depending on the position of the locking unit relative to the locking rail, in particular in the form of locking pins.
- the locking unit on the one hand and the locking rail on the other hand can be attached/formed, for example, to two seat rails that can be moved relative to one another. This makes it possible to create a locking device for longitudinal seat adjustments.
- a respective locking opening of the locking rail comprises, for example, two transverse edges spaced apart from one another along the adjustment direction (which each run essentially transversely to the adjustment direction) and two longitudinal edges spaced apart from one another perpendicular to the adjustment direction (which each run essentially along the adjustment direction).
- the longitudinal edges and the transverse edges together delimit a respective locking opening, the corners of which can be angular or rounded.
- the transverse edges are characterized in that they limit the extent of the locking openings along the adjustment direction, and the longitudinal edges limit the extent of the locking openings transversely to the adjustment direction.
- the locking openings are usually dimensioned in such a way that the locking openings have a greater extent along the adjustment direction than transversely thereto.
- the extent of the locking openings along the adjustment direction is advantageously so large that a respective locking element, viewed along the adjustment direction, can engage in an associated locking opening while resting against one or the other transverse edge. The said extent of the locking openings along the adjustment direction is therefore greater than the extent of a respective locking element along this direction.
- the locking device By means of the locking device, a fine adjustment of the position of the locking unit relative to the locking rail is made possible using a limited number of locking elements that can engage in the spaced-apart locking openings of the locking rail.
- a locking element immersed in a locking opening can be supported on one of the two locking webs or the transverse edge formed thereby.
- the dimensions and (periodic) distances of the locking openings along the adjustment direction as well as the (periodic) distances between the locking elements are selected, for example, according to the vernier principle.
- the said distances or periods are coordinated in such a way that in every position of the locking unit relative to the locking rail, at least two locking elements are always aligned with the locking openings and can be inserted into them (whereby they are then supported in different directions - viewed along the adjustment direction - on a respective transverse edge of the respective associated (long-hole-shaped) locking opening).
- one locking element supports the locking unit in one possible adjustment direction and another locking element supports it in the opposite adjustment direction. If the locking elements are lifted out of the locking openings - using a locking mechanism provided for this purpose - the locking unit can be freely adjusted relative to the locking rail or the respective associated seat components.
- Narrow locking bars would be advantageous in terms of finely adjusted seat components, but considerable forces can act on the locking bars in the event of a crash, so that tearing of the locking bars must be prevented by appropriate dimensioning.
- each latching opening usually run straight, but can also run curved (in sections) - especially in the corner areas.
- a generic locking device and a generic seat rail are known from DE 20 2005 003 626 U1 and EP 1 316 465 A1.
- the locking device is used in particular to lock an adjustment position of two seat elements of a vehicle seat that are movable relative to one another, which was previously reached by means of a suitable adjustment device, such as in a longitudinal rail guide for adjusting the seat position in the longitudinal direction of the vehicle.
- a suitable adjustment device such as in a longitudinal rail guide for adjusting the seat position in the longitudinal direction of the vehicle.
- One rail of the longitudinal rail guide is connected to the locking rail and another rail is connected to the locking unit of the locking device.
- the locking device can also be used to lock other adjustment devices with components that are movable relative to one another, in particular that are longitudinally adjustable relative to one another.
- the locking openings can also be arranged one behind the other along a curved path, such as a circular path. The adjustment direction is then determined locally from a tangent to the relevant curve.
- the locking device In addition to comfort functions, namely locking seat components as simply, quietly and reliably as possible (after they have been adjusted as desired), the locking device should also fulfil very important safety functions. In the event of a crash, the locking elements of the locking unit must not come out of engagement with the locking openings of the locking rail. Otherwise, the seat components locked together in this way could move towards each other in an uncontrolled manner.
- locking elements in the form of locking pins are known from EP 1 316 465 A1, which have a cylindrical shaft provided with a grooved area for guiding the locking pins in a pin bore, wherein a conically tapering section and then a further, comparatively short cylindrical section are connected axially to that cylindrical shaft towards the lower free end of the locking pins.
- a vehicle user should be able to lift the locking elements out of the locking openings with little effort using a release lever provided for this purpose in order to be able to readjust the seat position.
- the steeper the cone angle is selected the lower the tendency for the locking elements to be pushed out in the event of a crash; but the greater the gradation of the locking and the forces that must be applied by a user to lift the locking elements out.
- the invention is based on the problem of further improving a locking device of the type mentioned at the outset with regard to the above-mentioned requirements.
- At least one of the locking elements has a notch which is arranged along the locking direction below the locking rail when the locking element is in engagement with one of the locking openings as intended.
- the notch can be arranged in particular below the locking rail in such a way that the notch comes into contact with one of the locking webs formed between the locking openings and hooks into it when the locking element is inclined with respect to the locking direction due to the action of external forces (e.g. in the event of a crash) - compared to its intended position in one of the locking openings - and moves (in the inclined position) against the locking direction relative to the locking rail upwards and/or when the locking element and/or the locking rail are moved upwards due to the action of external forces (e.g. in the event of a crash). )forces.
- Such a hooking of the notch with one of the locking webs should not occur, however, if the locking element is lifted out of a locking opening against the locking direction while it is aligned along the locking direction as intended, i.e. in particular when the locking device is used as intended in the absence of crash forces.
- the solution according to the invention makes it possible to counteract, by simple means, a "jumping" of a respective locking element out of the associated locking opening under the influence of (crash) forces and thus to prevent unintentional unlocking of the locking device in the event of a crash.
- a respective notch can be formed by at least one groove on the locking element, which, for example, runs around the locking element.
- a plurality of notches, and accordingly possibly a plurality of grooves can also be provided on a respective locking element, which can be arranged one behind the other in particular along the locking direction.
- the locking elements can be designed as locking pins which extend along the locking direction and are guided along the locking device so as to be longitudinally movable. Furthermore, each of the locking elements can have a notch.
- the at least one notch of a respective locking element is arranged in particular outside the conically tapered section with which the locking element is supported on one of the locking webs, e.g. by forming the notch at the lower end region of the conically tapered section in the locking direction (which, when used as intended, in the absence of crash forces, does not rest against one of the locking webs).
- the locking elements are designed in a further development in such a way that the conically tapering section of a respective locking element in If a cylindrical section of the locking element adjoins the locking direction axially (downwards), then the notch can be located or formed at the transition from the conically tapering section to the cylindrical section of the locking element adjoining downwards - or also on the cylindrical section adjoining downwards itself.
- the notch can have a variety of shapes in cross-section, e.g. approximately semicircular, polygonal (possibly with rounded corners), etc.
- the notch has a sharp-edged section at its lower limit along the locking direction, via which the notch can hook with a locking web adjacent to a locking opening when the locking element comes into an inclined position with respect to the locking direction and moves upwards relative to the locking rail against the locking direction.
- the notch is advantageously free of sharp-edged sections at its upper limit along the locking direction, so that the notch does not get caught as far as possible with a locking web adjacent to the locking opening when the locking element moves downwards along the locking direction.
- a longitudinal rail guide for a motor vehicle seat with a locking device according to the invention is realized by the features of claim 19. Advantageous further developments thereof arise from claim 20.

- Figure 2 is a schematic side view of another embodiment of a locking device with a locking rail and a locking unit associated with the locking rail;
- Figure 3 shows a further development of an arrangement according to Figure 2
- Figure 4A shows a detail of the arrangement according to Figure 3 with a locking element of the locking unit which engages with a locking opening of the locking rail;
- Figure 4B shows the detail from Figure 4A, in a state in which the
- Figure 5A shows a first embodiment of the locking rail end of a
- Figure 5B shows a second embodiment of the locking rail-side end of a locking element of the locking unit
- Figure 5C shows a third embodiment of the locking rail end of a
- Figure 5D shows a fourth embodiment of the locking rail end of a
- Figure 6A shows a further development of the locking rail-side end of a locking element according to Figures 5A to 5D;
- Figure 6B shows the further development according to Figure 6A in a state in which the
- Locking element engages with a locking bar.
- the locking device shown in Figure 1 has a locking unit 1, which is assigned to the upper rail of a seat longitudinal adjustment and is firmly connected to it, for example, and a locking rail 2, which is correspondingly assigned to the lower rail of the seat longitudinal adjustment and is firmly connected to it.
- the locking rail 2 can be a component manufactured separately from the lower rail or a component formed integrally thereon.
- the locking rail 2 contains several locking openings 21 arranged (periodically) one behind the other along an adjustment direction E, which are separated from one another by locking webs 22.
- the locking unit 1 arranged above the locking rail 2 comprises several, in the present embodiment four, locking pins 5, 6, 7, 8, which (along the Adjustment direction E) are arranged at a constant distance from one another, the distance between the center axes of adjacent locking pins 5, 6, 7, 8 in the exemplary embodiment being smaller than the period of the locking openings 21 and locking webs 22 of the locking rail 2.
- the locking pins 5-8 have a cylindrical shaft 50 which is closed at its upper end by a head or collar 52 and which at its lower end merges into a conical (truncated cone-shaped) end section 51 on the locking rail side.
- the shafts 50 of the locking pins 5, 6, 7, 8 are movably guided in an (upper) bearing part 3 - by means of bearing openings there - and in a (lower) guide of a guide device 4 in the locking direction R of the locking pins 5, 6, 7, 8, wherein a number of guide bores or guide channels 41, 42, 43, 44 corresponding to the number of locking pins 5, 6, 7, 8 is provided as the guide means of the guide device 4, in which the shafts 50 of the locking pins 5, 6, 7, 8 are guided (e.g. with some play).
- Compression springs 10, 11, 12, 13 are arranged between the upper bearing part 3 and a recess 54 of the locking pins 5, 6, 7, 8, which serves as a stop, and which pre-tension the locking pins 5, 6, 7, 8 assigned to the locking openings 21 of the locking rail 2 along the locking direction R towards the locking openings 21.
- a release lever 9 is arranged between the upper head 52 of the locking pins 5, 6, 7, 8 and the bearing part 3 of the guide device, which, when pivoted, pulls the locking pins 5-8 in a locking position against the locking direction R out of the locking with the locking rail 2, so that the parts of the vehicle seat that are adjustable relative to one another are released for an adjustment process.
- the release lever 9 acts on all locking pins 5-8 together in order to move the locking pins 5-8 in a locking position out of that position.
- the section of the shafts 50 of the locking pins 5 to 8 between the recess 54 and the beginning of the conical or truncated cone-shaped section 51 be provided with a thread structure, as described in DE 20 2005 003 626 U1.
- Such a thread structure not only prevents the locking pins 5-8 from snagging or tilting in the guide holes or guide channels 41-44 of the lower guide 4, but also causes the locking pins 5-8 to self-lock in the event of a crash when a locking pin 5-8 is locked into a locking opening 21 of the locking rail 2 or a flank of its conical or frustoconical section 51 rests against a locking web 22 of the locking rail 2.
- the thread structures can be designed, for example, as a fine thread, which allows a high degree of accuracy of fit of the locking pins 5, 6, 7, 8 in the lower guide 4 of the guide device.
- a locking pin 8 is completely immersed in a locking opening 21 and is supported on a locking web 22, while another locking pin 7 is supported with a flank of its conical (truncated cone-shaped) end section 51 or an adjoining (possibly rounded) insertion bevel partially immersed on the inside of a locking web 22 of the locking rail 2.
- the two remaining locking pins 5 and 6 rest with the front side of their conical end section 51 on the top of two locking webs 22 as a result of the spring preload.
- release lever 9 If the release lever 9 is moved against the locking direction R to unlock the locking device, it first rests against the head 52 of one locking pin 8 and moves this against the locking direction R and against the preload force of the compression spring 13 out of its engagement with the locking rail 2 until the release lever 9 rests against the underside of the head 52 of the other locking pin 7 and also pulls this out of the locking position.
- the angle of inclination of the conical (truncated cone-shaped) end sections 51 of the locking pins 5-8 is selected such that the locking pins 5-8 cannot be pushed out of the locking openings 21 assigned to them by crash-related very large forces acting along the adjustment direction E if the locking pin in question is not located with its shaft 50 within the locking opening 21, but rests with the flank of the conical end section 51 on a locking web 22 of the locking rail 2.
- Adjustment direction E as the direction along which two components of a vehicle seat (one with the locking rail and one with the locking unit) are adjustable relative to each other.
- the locking openings are located one behind the other in the adjustment direction within an “adjustment level”.
- Locking direction R a direction approximately perpendicular to the adjustment direction E and the adjustment plane, along which the locking elements can be moved relative to the locking rail in order to engage or disengage them therefrom.
- the adjustment direction E, locking direction R and transverse direction Q thus form a kind of three-dimensional spatial system.
- the locking openings 21 of the locking rail 2 which are arranged one behind the other along the adjustment direction E (and spaced apart from one another by webs 22), are designed with regard to their extent (length) along the adjustment direction E such that a respective locking element 5, 6, 7 of the associated locking unit - viewed along the adjustment direction E - can engage in a respective locking opening 21 at different points.
- the locking elements 5, 6, 7 In the locking device as shown in Figure 2, in the locked state, two of the three locking elements 5, 6, 7 are engaged with one of the locking openings 21 of the locking rail 2, while another locking element rests on one of the locking webs 22.
- the locking elements 5, 6, 7 can be spring-elastically pre-tensioned along the locking direction R (perpendicular to the adjustment direction E and the transverse direction Q) towards the locking rail 2, as already explained with reference to Figure 1.
- the locking elements 5, 6, 7 are each conical at their end section 51 on the locking rail side, such that they taper towards their free end on the locking rail side. In the locked state, a respective locking element 5, 6, 7 rests on one of the transverse edges 211, 212 of the associated locking opening 21 via this end section 51 on the locking rail side.
- the maximum possible immersion depth of the locking elements 5, 6, 7 into a respective latching opening 21 is limited by a head 52 which is arranged or formed on the free end of a respective locking element 5, 6, 7 facing away from the latching rail 2 and which forms a stop for limiting the immersion depth of the locking elements 5, 6, 7.
- one of the locking elements (5) is completely immersed in an associated locking opening 21; i.e., a deeper immersion of the locking element in question is not possible due to the head 52 acting as a stop.
- a further locking element 6 is partially immersed in an associated locking opening 21; and a third locking element 7 rests on one of the locking webs 22.
- the fully or partially immersed locking elements 5, 6, 7 each rest with their conical end section 51 on one of the locking webs 22 delimiting the locking opening 21.
- a guide device 4 arranged above the locking rail 2 with guide openings 41, 42, 43 for the locking elements 5, 6, 7 is provided.
- the locking elements 5, 6, 7 are each accommodated in bearing openings 31, 32, 33 of a bearing part 3 (for example in the form of a bearing or support plate).
- the head 52 of a respective locking element 5, 6, 7 is located in front of the side of the bearing part 3 facing away from the locking rail 2.
- An unlocking lever 9 engages between the heads 52 of the locking elements 5, 6, 7 and the bearing part 3, with which the locking elements 5, 6, 7 can be lifted out of the locking openings 21 (by pivoting the same), and specifically together (whereas the locking elements 5, 6, 7 engage in the locking openings 21 independently of one another under the effect of spring-elastic forces, as explained with reference to Figure 1).
- the locking elements 5, 6, 7 and the associated guide device 4 as well as the bearing part 3 and the release lever 9 together form the locking unit 1 of the locking device - already described with reference to Figure 1 for another embodiment - which can be moved or displaced along the adjustment direction E relative to the locking rail 2.
- the locking unit 1 on the one hand and the locking rail 2 on the other hand are each connected to one of two seat components that can be moved longitudinally relative to one another, the latter can be moved by means of the The locking device formed by the locking unit 1 and the locking rail 2 can be locked in different relative positions, wherein the locking can be canceled by means of the release lever 9 for a new adjustment of the relative position along the adjustment direction E.
- the locking rail 2 can also be formed in one piece on the associated seat component.
- the two seat components can in particular be two rails of a longitudinal rail guide for a motor vehicle seat.
- Figure 3 shows a further development of the locking device from Figure 2, wherein a significant difference (besides the more detailed representation, including compression springs 11, 12, 13 and a thread structure 55 on the shaft 50 of the locking elements 5, 6, 7) is that the locking elements 5, 6, 7 are each provided with a notch 56, here specifically formed by a circumferential groove 57, which is arranged along the locking direction R below the locking rail 2 when the corresponding locking element 5, 7 is in engagement with one of the locking openings 21 as intended, see also the enlarged detail according to Figure 4A.
- the respective notch 56 or groove 57 is arranged below the locking rail 2, while the locking element 5, 6, 7 is in engagement with one of the locking openings 21 as intended, such that the notch comes into contact with one of the locking webs 22 and hooks into it when the locking element 5, 6, 7, due to the action of external (crash) forces - compared to its intended position in one of the locking openings 21 - comes into an inclined position with respect to the locking direction R and moves upwards relative to the locking rail 2 against the locking direction R or when the locking element 5, 6, 7 and/or the locking rail 2 are deformed under the action of the external forces - alternatively or in addition to the inclined position.
- the notch 56 is arranged along the locking direction outside (or more precisely below) the areas of the conically tapered section 51 of a locking element 5, 6, 7, with which the locking element 5, 6, 7 is intended to be supported laterally on one of the locking webs 22 when it is locked into an associated locking opening 21, namely, for example, on a lower end area of the conically tapered section 51 along the locking direction R.
- the conically tapering section 51 of a respective locking element 5, 6, 7 is connected downwards in the locking direction R, i.e. to the towards the free end on the locking rail side, there is also a (relatively short) cylindrical section 53 of the locking element 5, 6, 7, wherein the notch 56 is formed at the transition of the conically tapering section 51 to the cylindrical section 53 of the locking element (5, 6, 7, 8) adjoining it downwards (in the form of a circumferential groove 57).
- the focus is particularly on the behavior of the locking elements 5, 6, 7 when subjected to crash forces that have a force component along the adjustment direction E and/or the transverse direction Q and thus cause an inclination of the locking elements 5, 6, 7 with respect to the locking direction R and/or a deformation of components of the locking device.
- the notches 56 are intended to counteract a "jumping" of a respective locking element 5, 6 or 7 - which is inclined and/or deformed in the event of a crash - upwards out of the associated locking opening 21 under the influence of the crash forces (specifically, for example, due to the belt forces that occur in the event of a crash when a user of the corresponding vehicle seat is caught by the seat belt), thus preventing unintentional unlocking of the locking device in the event of a crash.
- the notch 56 should not get caught on one of the locking webs 22 if a locking element 5, 6, 7 is lifted out of a locking opening 21 in the opposite direction to the locking direction R using the release lever provided for it, while it is aligned along the locking direction (without a crash-related inclination), see Figure 4B.
- the locking device is used as intended in the absence of crash forces, there should be no snagging between the notch 56 and the locking web 22.
- a respective notch 56 or the corresponding groove 57 can be realized in different configurations with regard to the cross-section, e.g. with a contour that is arcuate in cross-section, in particular circular in shape, or with a polygonal, in particular triangular or square, cross-section, optionally with rounded corners.
- the locking elements 5, 6, 7 can advantageously be round in cross-section, in particular circular. However, a polygonal cross-section of the locking elements is also possible.
- the conical end sections form a (truncated) cone, in the second case a pyramid or a truncated pyramid.
- a slightly inclined mounting of the Locking elements may be useful to ensure a linear alignment at the edges or corners of an associated locking opening.
- the notch 56 or the corresponding groove 57 has a sharp-edged section 59a at its lower limit 59 along the locking direction R, via which the notch 56 or groove 57 can hook into a locking web 22 bordering a locking opening 21 when the locking element 5, 6, 7 comes into an inclined position with respect to the locking direction R and moves upwards relative to the locking rail 2 against the locking direction R, cf. Fig. 6B.
- the notch 57 or groove 57 is advantageously free of sharp-edged sections at its upper limit 58 along the locking direction R, e.g. provided with rounded portions 58a and/or bevels, so that the notch 56 or groove 57 does not get caught as far as possible with a locking web 22 adjacent to a locking opening 21 when the locking element 5, 6, 7 moves downwards along the locking direction R.
