Detailed description of the invention
as shown in Figures 1 to 6, automobile seat for child comprises base 1, seat 2, and the angle adjusting mechanism 3 for adjusting seat 2 to proper angle, for by seat 2 and the lockout mechanism of base 1 in the relative locking of proper angle.
in this example, in the left and right of automotive seats, two sides are symmetrically arranged with angle adjusting mechanism 3.Each angle adjusting mechanism 3 comprises first connecting rod 30 and second connecting rod 31, the upper end of first connecting rod 30, second connecting rod 31 is rotationally connected by the first pivot A, the second pivot B and seat 2 respectively, the bottom of first connecting rod 30, second connecting rod 31 is rotationally connected by the 3rd pivot C, the 4th pivot D and base 1 respectively, and the first pivot A, the second pivot B, the 3rd pivot C and the 4th pivot D parallel and all extend along the left and right directions horizontal direction of seat 2.First connecting rod 30, seat 2, second connecting rod 31 and base 1 form four-bar linkage, and the first pivot A, the second pivot B, the 3rd pivot C and the 4th pivot D form tetragonal four summits.In the time of lockout mechanism release, operation seat 2 or the parts that are fixedly connected with it, described seat 2 can be rocked back and forth by relative described seat 2 with second connecting rod 31 by first connecting rod 30, to adjust the angle of seat 2, in the time of selected suitable angle, lock described lockout mechanism, fixing seat 2 is with respect to the angle of base 1.
as illustrated in Figures 5 and 6, this routine lockout mechanism comprises two lock cells 5 of left and right two sides that are symmetricly set on automotive seats.Lock cell 5 comprises the different lockhole 50 of multiple height being opened on base 1, be slidably arranged on seat 2 and the locking bolt 51 of the locking that can match with described multiple lockholes 50, the line of centers of lockhole 50, the direction of slip of locking bolt 51 are all along the left and right directions horizontal-extending of automotive seats.Lockout mechanism also comprises for making locking bolt 51 towards the elastic component 6 of lockhole 50 direction motions with for making locking bolt 51 depart from the unlock piece of lockhole 50.In this example, elastic component 6 is specially spring, its between the locking bolt 51 of two lock cells 5 and both ends inconsistent with the locking bolt 51 of two lock cells 5 respectively.Be provided with collet 8 in the bottom of seat 2, unlock piece is the release handle 7 being fixed on collet 8, on this release handle 7, offer two symmetrical elongated holes 70, from one end, (rear end) (front end) becomes greatly distance between two elongated holes 70 gradually towards the other end, and one end portion of the locking bolt 51 of two lock cells 5 is respectively through two elongated holes 70 and be relatively mounted slidably.Referring to Fig. 5, in the time that lock cell 5 is in the lock state, locking bolt 51 is positioned at the front end of elongated hole 71, now, under the effect of elastic component 6, locking bolt 51 stable in lockhole 50, by relative with base 1 seat 2 locking.Referring to Fig. 6, while carrying out release, pull forward release handle 7(locking bolt 51 to slide to rear end with respect to release handle 7 from the front end of elongated hole 70), elastic component 6 is compressed, and locking bolt 51 is deviate from and release from lockhole 50.
although be arranged with 2 angle adjusting mechanisms in this example in automotive seats, only establish 1 angle adjusting mechanism and be also fine.
adopt the automobile seat for child of structure of the present invention, when seat 2 is adjusted after angle with respect to base 1 by angle adjusting mechanism 3, locking bolt 51 through certain lockhole 50 on base 1, guarantees that seat 2 is firmly connected with base 1, as shown in Fig. 1, Fig. 3 and Fig. 5 under the elastic force effect of elastic component 6.In the time need to adjusting the angle of seat 2, pull forward release handle 7, utilize the elongated hole 70 on it to pull locking bolt 51 compression elastic pieces 6, after elastic component 6 is compressed, locking bolt 51 is deviate from from lockhole 50, and lock cell 5 releases, as shown in Fig. 4 and 6.Hold operation handle 7, make it remain on unlocked position motionless and seat 2 is rocked back and forth by first connecting rod 30 seat 2 relative to second connecting rod 31, so that seat 2 is adjusted to proper angle, regulate after angle, decontrol release handle 7, when locking bolt 51 slips into this position under the elastic force effect of elastic component 6, in corresponding lockhole 50, guarantee that seat 2 is firmly connected with base 1, as shown in Figure 2.
as mentioned above, the present invention utilizes four-bar linkage to carry out the angle of adjusting seat, not only simple in structure, and operation is light and handy convenient.
above the present invention is described in detail; its object is to allow the personage who is familiar with this art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; the equivalence that all Spirit Essences according to the present invention are done changes or modifies, and all should be encompassed in protection scope of the present invention.
