Embodiment
As shown in Figures 1 to 6, automobile seat for child includes base 1, seat 2, for adjusting seat 2 to the angle of proper angle
Governor motion 3, for the locking mechanism for locking seat 2 and base 1 relatively in proper angle.
In this example, angle adjusting mechanism 3 is symmetrically arranged with the side of left and right two of automotive seats.Each angle adjusting mechanism 3 is wrapped
First connecting rod 30 and second connecting rod 31 are included, first connecting rod 30, the upper end of second connecting rod 31 pass through the first pivot A, second respectively
Pivot B is rotated with seat 2 and is connected, and first connecting rod 30, the bottom of second connecting rod 31 pass through the 3rd pivot C, the 4th pivot D respectively
Rotate and be connected with base 1, the first pivot A, the second pivot B, the 3rd pivot C and the 4th pivot D are parallel and along a left side for seat 2
Right direction horizontal direction extends.First connecting rod 30, seat 2, second connecting rod 31 and base 1 constitute quadric chain, the first pivot
A, the second pivot B, the 3rd pivot C and the 4th pivot D constitute four summits of quadrangle.When locking mechanism is unlocked, seat is operated
Chair 2 or the part for being secured to connection, allow the seat 2 to pass through first connecting rod 30 and the relatively described seat of second connecting rod 31
2 rock back and forth, to adjust the angle of seat 2, when selecting appropriate angle, lock the locking mechanism, fixing seat 2 is relative
In the angle of base 1.
As it can be seen in figures 5 and 6, this example locking mechanism includes two lock cells for being symmetricly set on the side of left and right two of automotive seats
5.Lock cell 5 includes being opened in multiple highly different lockholes 50 on base 1, is slidably arranged on seat 2 and can
It is engaged the locking bolt 51 of locking with the multiple lockhole 50, the center line of lockhole 50, the glide direction of locking bolt 51 are each along automobile
The left and right directions of seat is horizontal-extending.Locking mechanism also includes being used to make the He of elastic component 6 that locking bolt 51 is moved towards the direction of lockhole 50
For making locking bolt 51 depart from the unlock piece of lockhole 50.In this example, elastic component 6 is specially spring, and it is located at two lock cells 5
Locking bolt 51 of between the locking bolt 51 and both ends respectively with two lock cells 5 is inconsistent.Collet 8, solution are provided with the bottom of seat 2
Latch fitting is to offer symmetrical two elongated holes 70 on the unblock handle 7 being fixed on collet 8, unblock handle 7, and two elongated
The distance between hole 70 is from one end（Rear end）Towards the other end（Front end）Become larger, the locking bolt 51 of two lock cells 5
One end is each passed through two elongated holes 70 and is mounted slidably relatively.Referring to Fig. 5, when lock cell 5 is in the lock state
