The present invention relates to a kind of new seat for automobile, particularly a kind of new seat of adjustable seat backrest front and rear angles.

In the prior art, the automotive seat great majority are to overturn foldingly forward, also cannot turn over and set level, and project organization is outmoded.95115997.6 patent of invention, though can overturn, mechanism is quite complicated, and manufacturing cost is higher.

The research document of relevant reduction auto cost is pointed out, a kind of back seat that can make the occupant enter two-door automobile easily need be provided, and be used for lade, the seat that need provide a kind of backrest slope of seat to regulate.

The objective of the invention is, provide a kind of both can overturn forward folding, the seat that can turn over again and set level, backrest slope can be regulated.

The objective of the invention is to finish as follows: a kind of by headrest 1, backrest 2, the seat that seat cushion 5 and bearing 6 are formed is characterized in that the mechanism of scalable backrest 2 comprises by latch hook handle 3, rotation regulating handle 4, pull back spring 9, seat base 10, limiting stopper 11, latch hook trace 12, cable brace 13, regulator bracket 14, regulating control 15, steel plate chip latch hook 16, lock ring 17, pin 18, spring cotter 19, the latch hook device that lacing wire support 20 is formed and by turnover hinge axle 7 forward, handle skeleton 21, bolt of rear end plate 22, seat base 23, bolt 24, hinge 25, the turnover hinge device that power assistant spring 26 and connecting panel 8 are formed.

The middle and upper part of backrest 2 is equipped with latch hook handle 3.Latch hook handle 3 is fixed on the handle skeleton 21 of backrest 2.The rotation regulating handle 4 of left side seat is installed in the rear positions in seat cushion 5 left sides.The rotation regulating handle 4 of right seat is installed in the rear positions on seat cushion 5 right sides.The inferoanterior of seat bearing 6 is established the hinge axis 7 that right seat overturns forward.The following rear of seat bearing 6 is provided with latch hook trace 12.Weld with two steel plate chip latch hooks 16 respectively at the two ends of latch hook trace 12.One end of cable brace 13 is connected with the lacing wire support 20 of latch hook handle 3.The other end of cable brace 13 is connected with steel plate chip latch hook 16.Cable brace 13 is connecting latch hook handle 3 and latch hook trace 12.Handle skeleton 21 and the welding of backrest skeleton.Handle skeleton 21 is connected with bolt of rear end plate 22 with latch hook handle 3.Seat base 23 is connected with bolt 24 with hinge 25.Hinge 25 is connected with hinge axis 7 with connecting panel 8.Power assistant spring 26 is installed on the hinge axis 7.Connecting panel 8 and body platform are with bolted connection.

Seat folded turnover forward is achieved in that with pulling moveable lock hook handle 3, has then opened steel plate chip latch hook 16, is axle with the hinge axis 7 that overturns forward, and backrest 2 can turn forward.Thereby, finished the control process forward of back of seat 2.At this moment, with hand propelled backrest 2, then seat can be an axle with hinge axis 7, forward upset and 5 one-tenth 53 ° of seat cushions.When unclamping latch hook handle 3, because the effect of pull back spring 9 and seat own wt can return to original position with seat.The steel plate chip latch hook 16 of steel plate chip enters in the lock ring 17.Seat is by locked.The material of steel plate chip latch hook 16 is the medium-carbon steel of 3-5 millimeters thick, preferably selects steel No. 35, or No. 45 steel.

The seat operation of setting level of turning over is, the rotation regulating handle 4 that rotates backward, and then backrest 2 can recede 101 °-180 °.Thereby, finished the control process backward of back of seat 2.

The present invention compares with the existing automotive seat that can adjust the backrest inclination angle, easy operating, flexibly and fast.

Below will do further detailed description to the present invention by embodiment shown in the drawings:

Fig. 1 is the lateral plan that right seat is in occupant's state;

Fig. 2 is the enlarged drawing of A to view;

Fig. 3 is the installation block diagram of latch hook handle;

Fig. 4 is the seat installation block diagram of turnover hinge forward.

As shown in Figure 1, a kind of seat of being made up of headrest 1, backrest 2, seat cushion 5 and bearing 6 is characterized in that the mechanism of scalable backrest 2 comprises latch hook handle 3, rotation regulating handle 4, hinge axis 7 and connecting panel 8.

As Fig. 1 and shown in Figure 2, latch hook handle 3 is fixed on the handle skeleton 21 of backrest 2.One end of cable brace 13 is connected with the lacing wire support 20 of latch hook handle 3.The other end of cable brace 13 is connected with steel plate chip latch hook 16.Seat cushion 5 and backrest 2 adopt the foamed plastic of 70-100 millimeters thick.The foamed plastic outsourcing is with the terylene composite material of seat special use.

As shown in Figure 3, latch hook handle 3 is installed on the handle skeleton 21 of backrest 2.This installation site meets physical activity labour-saving needs.When latch hook handle 3 was upwards mentioned, then lacing wire support 20 was driving cable brace 13 and is upwards moving.Thereby making cable brace 13 bonded assembly steel plate chip latch hooks 16, is fulcrum and upward movement with latch hook trace 12.The stretching of limiting stopper 11 restriction pull back springs 9.At this moment, made the latch hook of steel plate chip latch hook 16, from lock ring 17, spun off.That is to say that steel plate chip latch hook 16 has been opened.

As shown in Figure 4, seat base 23 is connected with bolt 24 with hinge 25.Hinge 25 is connected with hinge axis 7 with connecting panel 8.Power assistant spring 26 is installed on the hinge axis 7.Connecting panel 8 and body platform are with bolted connection.
