Definitions
- the invention relates to a spring, in particular for a locking device of a vehicle seat, with the features of the preamble of claim 1.
- a known spring of the type mentioned is a leg spring with two legs and a plurality of turns therebetween, which are wound with a constant winding diameter around an axis, wherein adjacent turns are offset from one another about the slope along the axis.
- the leg spring is tensioned by the two legs are pivoted relative to each other about the axis. Accordingly, the built-up bias acts in the circumferential direction.
- the leg spring is particularly preferred if the dimension along the axis should remain constant and the space is limited in the radial direction.
- a coil spring can be used in which all turns with continuously changing winding diameter are laid as a spiral in one another. The spiral spring is particularly preferred when the space in the axial direction is severely limited, but is sufficiently available in the radial direction.
- the invention is based on the object to improve a spring of the type mentioned. This object is achieved by a spring with the features of claim 1. Advantageous embodiments are the subject of the dependent claims.
- the spring configured according to the invention combines the advantages of a leg spring with the advantages of a spiral spring, so that overall there is a small space requirement.
- the reduction of the slope and thus the overall axial dimension can be achieved by different turns diameter of adjacent turns. In the case of, for example, two different winding diameters, the turns after the next come into contact with each other, so that the pitch can be reduced to half the cross-sectional diameter. For three turns, preferably the middle turn has a smaller turn diameter.
- Fig. 2 is an illustration of the pulled along the axis A apart embodiment
- Fig. 3 is a partial view of the embodiment with a view perpendicular to the axis A.
- a locking device for a vehicle seat has a movable pawl and a mating element cooperating with the pawl in the locked state.
- the pawl is secured in the locked state by at least one securing element.
- two securing elements namely a prestressed clamping eccentric, which normally acts on the pawl with an eccentrically curved surface outside the self-locking, and a catching piece, which is supported in the event of a crash slightly due to an opening moment moving in the opening direction pawl by within the self-locking rests against the pawl, so that it can not transmit any opening moment.
- Such locking devices are for example in the DE 44 39 644 A1, DE 103 04 574 B4 and DE 10 2006 044 489 A1, the relevant disclosures of which are expressly incorporated by reference.
- a spring 10 is presently provided for biasing the securing element of the locking device, more precisely of the clamping eccentric.
- the spring 10 is formed from a spring wire with present constant cross-section.
- the cross section is in the present case circular with a diameter which is referred to below as the cross-sectional diameter q.
- the cross-sectional diameter q should correspond to the dimension of the cross section parallel to the axis A.
- the spring 10 is formed as a leg spring, that is, the spring 10 has two legs 10a at the end, between which at least one first turn 10b, which is completely wound around the axis A, and at least one adjacent, possibly incompletely wound around the axis A around second winding 10b, which is arranged offset along the axis A, are provided.
- the axis A defines the directions used here.
- the legs 10a are, for example tangentially, radially or parallel to the axis A of the windings 10b. In the present case, two complete and one incomplete turns 10b are formed, ie over a part of the circumference of the spring 10 two and over the other part of the circumference three turns 10b are present.
- the windings 10b are wound in a circle around the axis A, with different diameters occurring in the present case.
- the distance between two windings 10b, by which the windings 10b are offset relative to one another along the axis A, ie the pitch (or pitch) h, can then be smaller than the cross-sectional diameter q (h ⁇ q).
- the pitch h can be reduced to half the cross-sectional diameter q, so that the following applies:
- the pitch h can be reduced to one third of the cross-sectional diameter q, etc.
