Definitions

  • the device includes a pair of components one of which is movable relative to the other and is to be fixed at an adjusted position with respect to the other component.
  • a pair of lock means coact with these components for releasably holding them in a selected position one with respect to the other.
  • One of the lock' means is movable to and from a locking position with respect to the other lock means, and a manually operable means coacts with this one lock means for displacing it between locking and unlocking positions.
  • this one lock means is capable of automatically returning from its unlocking position to its locking position, independently of the manually operable means, in response to a speed of movement of one of the components relative to the other which is greater than a predetermined speed. Therefore, if, when the one lock means is in its unlocking position, one of the components should suddenly move at high speed relative to the other, the one lock means will automatically reassume its locking position to prevent the high-speed movement of the one component.
  • the present invention relates to adjusting devices for releasably holding one adjustable component at a selected position with respect to another component.
  • This device of the invention is particularly suited for releasably holding a tiltable backrest of an automobile seat at a selected angular position with respect to the lower seat portion of the automobile seat.
  • the components are held in their adjusted position by way of a pair of lock means one of which is displaceable between a locking and unlocking position with respect to the other. When this one lock means is in its unlocking position the position of the components can be adjusted one relative to the other.
  • lock devices for tiltable backrests for example in the form of self-locking drives, which also operate during adjustment of the inclination of the backrest to secure the backrest against tilting movement under the action of a load which acts on the backrest.
  • Such known devices have the disadvantage that they permit only a relatively slow rate of adjustment to be carried out, which is of a particular disadvantage in the case where the backrest is to be tilted forwardly through a large distance so as to facilitate entry of an occupant into the rear part of the vehicle.
  • a pair of lock means which coact with a pair of adjustable components one of which is adjustable relative to the other.
  • one of the lock means is displaceable from a locking position to an unlocking position with respect to the other lock means.
  • a manually operable means coacts with this one lock means for displacing it between its locking and unlocking positions.
  • this one lock means will respond independently of the manually operable means to return to its locking position and thus retard the unexpected movement of the one adjustable component.
  • the one lock means can respond or automatically turn to its locking position either as a result of its own inertia, this one lock means being provided with a suitable mass for this purpose, or it can be shifted back to its locking position in response to a component of force emanating from the adjustable component when the latter moves at a speed greater than a given speed.
  • a means in the form of a suitable spring for example, can act on the one lock means for urging it to its unlocking position, so that this one lock means will return to its locking position only in opposition to the spring.
  • the displacement of the one lock means between its locking and unlocking positions requires movement of the one lock means along only a relatively short distance, so that a very rapid return of the one lock means to its locking position can be achieved.
  • the manually operable means which coacts with the one lock means is in the form of a cam having camming slots which coact with cam followers for assuring displacement of the one lock means from its locking to its unlocking position, these slots having with respect to the cam follower pins a Width substantially greater than the thickness of these pins when the one lock means is in its unlocking position to assure the possibility of unrestrained returned movement of the one lock means to its locking position automatically and independently of the manually operable means.
  • camming slots of this type it is also possible to provide the slots with a configuration which will exclude the possibility of return of the one lock means automatically to its locking position, if desired.
  • the one lock means which is displaced between the locking and unlocking positions takes the form of a nut surrounding and threadedly engaging a spindle which has a thread of large enough pitch to result in rotary movement of the nut in response to axial movement of the spindle.
  • This spindle moves axially in response to adjusting of the one component, and when the latter is unexpectedly subjected to a load large enough to provide a speed of movement exceeding a predetermined speed of movement, the spindle will have an axial thrust with respect to the nut sufliciently great to shift the latter back to its locking position, even in opposition to a spring which tends to urge the nut away from its locking position.
  • FIG. 1 is a partly broken away fragmentary side elevation of one possible embodiment of a structure according to the invention
  • FIG. 2 is a transverse sectional elevation of the structure of FIG. 1 taken along line 11-11 of FIG. 1 in the direction of the arrows;
  • FIG. 3 is a transverse section of the structure of FIG. 1 taken along line IIIIII of FIG. 1 in the direction of the arrows;
  • FIG. 4 is a schematic fragmentary side elevation showing a difierent type of cam which may be used with the embodiment of FIGS. 1-3;
  • FIG. 5 is a schematic side elevation showing a further embodiment of a cam structure which may be used with the assembly of FIGS. l3;

  • FIG. 7 is a fragmentary sectional elevation showing the structure at the lower left portion of FIG. 6, the section of FIG. 7 being taken in a plane which contains the axis of a. spindle of the device;
  • FIG. 8 is a fragmentary top plan view of the structure shown at the lower left portion of FIG. 6.
  • the structure illustrated therein includes a lower stationary component 1 which is adapted to be fixed to and form part of a lower seat portion of an automobile seat, for example.
  • This lower component 1 is pivotally connected with a swingable component 2 by way of a pivot pin 3 carried by the component 1 and forming a guide means which guides the component 2 for movement with respect to the component 1.
  • the component 2 is connected to and forms part of the backrest of an automobile seat, in the example illustrated in this application so that this backrest can be swung with respect to the seat portion to a selected angular position.
  • a lock means is operatively connected with the components 1 and 2, and this lock means includes in FIGS. l3 a circular ring gear 4 having inner teeth.
  • the ring gear 4 is fixed to the stationary component 1 and concentrically surrounds the pivot pin 3.
  • the lock means further includes a gear 5 which meshes with the inner teeth of the ring 4 and which is supported for rotary movement on the circular periphery of a disc or plate 6 which eccentrically surrounds the pin 3, the plate 6 forming with the pin 3 a guide means for guiding not only the swingable component 2 but also the gear 5 of the lock means.
  • the plate 6 is freely turnable about the pin 3 and is fixed to the component 2 for swinging movement with the latter about the pin 3, while the gear 5 can turn freely on the periphery of the eccentric plate 6.
  • the lock means 4, 5 has the construction of a planetary drive since during swinging of the component 2 with respect to the component 1 the gear 5 will planetate along the inner teeth of the gear 4'.
  • the elements 4 and 5 of this lock means define between themselves an elongated curved space of substantially sickle-shape configuration, and a second lock means coacts with the lock means 4, 5 for releasably holding the component 2 at a selected angular position with respect to the component 1.
  • This second one of the pair of lock means includes a pair of lock members 7 and 8 in the form of elongated curved plates of substantially wedge-shape configuration having shapes which conform to the space between the elements 4 and 5 at the region of the ends of this space.
  • the lock elements 7 and 8 extend from the part of the sickleshaped space which is of maximum width to the opposed ends thereof which are of minimum width.
  • the lock members 7 and 8 which are spaced from each other engage the tips of the teeth of the lock elements 4 and 5 for pressing against these teeth to prevent relative movement between elements 4 and 5 when the lock means 7, 8 is in its locking position. If the component 2 tends to swing in a counterclockwise direction, as viewed in FIG. 1, while the lock means 7, 8 is in its locking position, then the element 5 will press radially against the element 8 to press the latter more tightly against the teeth of the element 4, so that the element 8 becomes transversely compressed between the elements 4 and 5, and in this way the pair of lock means coact to prevent movement of the component 2 in a counterclockwise direction, as viewed in FIG. 1. If there is a tendency for the component 2 to turn in a clockwise direction, as viewed in FIG.
  • the swingable component 2 carries a pivot pin 10 which supports a cam plate 9 for swinging movement.
  • This cam plate 9 forms part of a cam means for controlling the positions of the elements 7 and 8, and for this purpose the cam plate 9 has camming edges 17 and 18 indicated in FIG. 1.
  • the cam means further includes cam-follower pins 7' and 8' respectively fixed to and extending perpendicularly from the elements 7 and 8 through slots 19 and 20' formed in the component 2, so that the pin 7' and 8 have distant from the lock elements 7 and 8 free end portions engaging, at their side surfaces, the camming edges 17 and 18.
  • the guide slots 19 and 20 extend along a circle which is concentric with the pin 3.
  • the configuration of the camming edges 17 and 18 is such that when the cam plate 9 is swung in a counterclockwise direction, as viewed in FIG. 1, the lock means 7, 8 is displaced to its locking position, so that the elements 7 and 8 are pushed apart from each other.
  • the turning moment required to turn the cam plate 9 is derived from a manually operable means in the form of a lever 11 accessible to the operator and forming an integral extension of the cam plate 9.
  • a spring 12 is operatively connected with the lever 11 to urge the latter to turn with the cam plate 9 in a counterclockwise direction, as viewed in FIG. 1, so that the spring 12 maintains the lock means 7, 8 in its locking position.
  • each of the springs 27 and 28 is the form of a substantially U-shaped spring element having one end fixed to the swingable component 2.
  • the free ends of the springs 27 and 28 press against the follower pins 7' and 8' at side surfaces thereof directed away from the camming edges 17 and 18, so that the springs 27 and 28 also function to maintain the follower pins 7 and 8' in engagement with the cam plate 9.
  • a force of inertia will act on the lock elements 7 and 8 in accordance with the mass thereof, particularly when the movement of the component 2 is accelerated.
  • This force of inertia acts on one of the elements 7 and 8 in the same direction as that in which the component 2 is turned with this force of inertia acting in the same direction on one element as the spring which presses against the follower pin thereof and acting on the other element in opposition to the force of the spring which presses against the follower pin thereof.
  • one of the springs 27 and 28 will urge one of the components 7 and 8 in a direction opposite to the force of inertia acting thereon.
  • the lock means 7 and 8 is capable of responding automatically to a speed of movement of the component 2 which is above a given speed for automatically assuming its locking position to prevent movement of the component 2 at a speed which is above a given speed.
  • the element -8 will automatically assume its locking position if the lock means 7, 8 happens to be unlocked and there is a sudden rearward thrust on the component 2 tending to swing the latter unexpectedly in a clockwise direction, as viewed in FIG. 1.
  • Such a sudden unexpected acceleration of the component 2 in a clockwise direction, as viewed in FIG. 1 will very effectively thrust the element 8 by inertia back to its locking position with the locking force increasing as the force tending to swing the component 2 in a clockwise direction increases, so that the greater the latter force the greater the force of inertia which presses the component 8 to its locking position to increase the locking action.
  • the cam plate 9 in the illustrated example is provided with an axially extending portion 9' (FIG. 3), and this extension 9 is fixed with a motion-transmitting tube 29 connected to a corresponding extension of a cam plate of the other mechanism at the other end of the seat, so that both of these mechanisms will be simultaneously actuated.
  • the width of the slots 31 and 32 is not uniform over their entire length.
  • the slot width only corresponds to the diameter of the follower pin at those ends of the slots 31 and 32 which respectively receive the follower pins when the lock means 7, 8 is in its locking position.
  • it is the lower end of the slot 31 which receives the pin 8' and has a width corresponding to the diameter of the pin 8 when the element 8 is in its locking position while the upper end of the slot 32 has a width corresponding to the diameter of the pin 7' and receives the pin 7' when the element 7 is in its locking position.
  • the configurations of the camming slots 31 and 32 are such that they will initially compel the lock means 7, 8 to move from its locking to its unlocking position, but when the elements 7 and 8 are in their unlocked positions, they are free to return under the force of inertia to their looking position.
  • the follower pins are free to move by inertia with the lock elements when the cam 30 and lever 11 have been displaced to a position corresponding to the unlocked position of the lock means 7, 8.
  • the slots 34 and 35 are respectively provided with extensions enabling the cam plate 33 to be swung beyond the position it normally assumes when the lock means 7, 8 is in its unlocking position.
  • the normal unlocking position of the cam can easily be noted and felt by the individual operating the lever 11 since the structure is designed to provide a substantially greater force resisting turning of the cam beyond its normal position when the lock means 7, 8 is unlocked. This results is achieved by way of a leaf spring 36 the force of which must be overcome when the lever 11 and cam 33 are displaced beyond the position they normally assume when the lock means is unlocked.
