• unlocking devices can be used for a variety of applications.
• unlocking devices with actuating magnets are preferable, since the pertinent actuating magnet, even in rough everyday use, such as occurring vibrations or shocks, experience proven to be reliable in use.
• the unlocking device according to the invention can be unlocked especially in the automotive sector safety-relevant components and bring to function, be it in the form of a roll bar to be erected, be it in the form of a moving headrest in the event of a crash to thus reducing the free impact between the occiput of the seat occupant and head impact area on the headrest, etc.
• the actuating magnet can be accommodated with operating part and movable control device in a very small space, so that can leave the pertinent devices to save space within motor vehicles. Due to the space-saving design, such unlocking devices can also be used there directly at the point of a tripping operation, where hitherto in the prior art, possibly only consuming to handle cables or Bowden cables over longer distances have accomplished the tripping operation.
• the invention has for its object to provide an unlocking available, in which the risk of such loss of Functional safety of an associated safety device is avoided.
• the peculiarity of the invention consists in the fact that a blocking part is provided for the guided in the housing part of the actuating magnet locking part, which holds the locking member in the release of the control part corresponding unlocked position, thereby preventing unwanted re-locking of the control part.
• the blocking part is formed by a bow spring, which is guided with its free spring ends at least partially along the housing part for movement between the blocking position, in which the locking member is held by the bow spring in the unlocked position, and a position in the locking part is released for re-locking the control part.
• the arrangement may preferably be made such that the bow spring is accessible for manual displacement from the blocking position out.
• the bow spring may be shaped so that the free spring ends in the blocking position between them form a nip for clamping the locking member located in the unlocking position.
• Angular guides are provided which, upon movement of the bow spring from the blocking position to the locking member releasing position, form control surfaces for the spring ends which spread them apart and expand the nip to release the locking member for return to the control member locking position.
• FIG. 1 shows a perspective view of a front view of the essential parts of the device according to the invention
• Fig. 5 is a partially cutaway housing of the device with inserted blocking element.
• the actuating magnet 12 has a bobbin 14 with a coil winding, not shown, in which a cylinder or rod-like actuating member 16 guided longitudinally movable is.
• the trained in the manner of a conventional electromagnet actuating magnet 12 is designed such that upon energization of the bobbin 14 via the connector 18, the actuating member 16 is pulled inward, ie in the direction of the Fig.2 seen in the direction of the rear biplane.
• a return spring (not shown in more detail) can reset the actuating part 16 in such a way that it projects beyond the front side of the bobbin 14, including the front side of the actuating magnet 12, with a predeterminable projection.
• the actuating part 16 is thus arranged to be movable along a first axis 20.
• the actuating member 16 is pulled by the actuating magnet 12 to the rear and thus releases a transverse to the first axis 20 pivoting path 22, which is shown in Figure 3 with an arrow and along this pivoting path 22, the control device 24 pivots in the clockwise direction about a second axis 26 which is parallel to the first axis 20.
• the pertinent second axis 26 is formed, for example, as a pivot axis or pivot pin and with its free ends so far ends in a housing part 28, preferably made of a suitable plastic material, out.
• the control device 24 has a locking part 30 which unlocks the movement path 32, illustrated in FIG.
• FIGS. 1 and 2 relate to the locked position for the control part 10, it can be seen that the locking part 30 at least partially surrounds the control part 10 and thus holds it in the locked position.
• the control device 24 has a pivoting lever 34, as shown in detail in Figure 4. This pivot lever 34 is, as already stated, guided about the second axis 26 pivotally in the housing part 28, which was omitted for ease of illustration in Figure 4.
• the pivot lever 34 is at its one free end in the unactuated state of the actuating magnet 12 in contact with the actuating part 16, wherein according to the illustration of Figure 4 just the operating member 16 is retracted into the bobbin 14 of the actuating magnet 12 and insofar the pivoting path 22 for the pivot lever 34 releases.
• this with its front side essentially forms a flat front surface with the front side of the bobbin 14 facing the observer of FIG.
• the pivoting lever 34 is still shown there in its unactuated position, so that in this respect the control part 10 is held in the locking position at the other end of the pivoting lever 34.
• the locking part 30 of the control device 24 is designed in the manner of a jaw or mouth opening 36 and thus the pertinent locking part 30 can be arranged centrally in the center of the device (see FIG an axial offset point 38 in order to ensure the pertinent center arrangement can.
• the jaw or mouth opening 36 pivots in a clockwise direction about the pivot axis 26 from the locked position according to FIGS. 1 and 2 into an unlocked position according to FIG.
• control part 10 provides a bow spring, preferably in the manner of a double bow spring 40 whose energy storage in the form of spring energy in the unlocked state allows pivoting along the path of movement 32 from the control device 24 for the control part 10, namely about a third axis 42, which in turn is parallel to the first and second axes 20,26. Due to the momentum of the control part 10 in the form of the double bow spring 40 so it is sufficient to trigger the actuating magnet 12 to make the unlocking so far externally controlled.
• the actuating magnet 12 is pot-shaped and has an annular coil body 14, the winding ends are connected to the connector 18 accordingly.
• an actuating part 16 of the bobbin 14 comprises a flat-cylindrical actuating rod, which has a similar cup shape to the annular bobbin 14 and is guided in this longitudinally movable.
• the pivoting lever 34 is at its one free, the operating part 16 end facing a claw-like tapered provided with a curvature which at least partially follows the curvature of the outer periphery of the actuating part 16 (see also Fig.2) ,
• the said double bow spring 40 with its bow part 44 engages in the locking position in the locking part 30 of the control device 24, wherein the two, the double arrangement concerning round springs 46, the third axis 42 include the center. If, as shown in FIG.
• the release device could again be "armed” by means of a corresponding return operation, which is prevented in the invention, for example because parts of a safety device (not shown) or the safety device itself are to be exchanged the strap part 44 again comes into unintentional engagement with the locking part 30 and its mouth and mouth opening 36. To prevent this, the locking part 30 is held in its unlocking position shown in Fig. 3. The purpose of this is shown in FIG Blocking member 48, which prevents unintentional re-locking of the control part 10.
• the blocking part 48 likewise consists of a bow spring 50 which, with its free spring ends 52 at least partially guided along the housing part 28, is movable into a position releasing the locking part 30.
• part of the wall of the housing part 28 is omitted in FIG. 5 with respect to the front view so as to illustrate the attack of the bow spring 50 on the upper side of the locking part 30.
• the bow spring 50 is shown as a blocking part in its blocking position. If the unlocking process is triggered, then the locking member 30 snaps up and comes into the nip between the spring ends 52nd The spring ends 52 then clamp between them a part of the locking member 30 such that it is held in the unlocking position of Figure 3. If, viewed in the direction of FIG.
• the bow spring 50 is now displaced downwards by hand, the free springs 52 slide along inclined guides 54 of the housing part 28, so that the spring ends 52 spread apart from one another and then the pivoting path for the locking part Release so far so that this can go back to the locked position.
• the locking member 30 snaps back up and takes in such a way the bow spring 50 with re-formation of the nip for the locking member 30, so that insofar this is then blocked again in its unlocked position and can not be unintentionally pivoted back into the locked position ,
• the unlocking device according to the invention can be used for a variety of applications, and instead of a control part 10 in the form of a double bow spring assembly 40, a simple spring (not shown) occur. Also, other technical components, such as parts of a roll bar system, of the jaw or mouth opening 36 of the locking member 30 hold, so that extent the scope is arbitrarily expandable.
• the solution according to the invention is also characterized in particular by the fact that the function control takes place via a single lever in the form of the pivoting lever 34.
