Abstract

end. The technical field to which the invention described in the claims belongs.

The present invention relates to a child safety seat of an automobile, and in particular, to solve the problem caused by the child safety seat is leaned forward when sudden braking.

I. The technical problem to be solved by the invention.

In general, a child safety seat of a car uses a separate safety seat that can be filled with a seatbelt mounted on a vehicle, and thus is exposed to considerable danger during sudden braking, and recently, a safety seat is classified into a fixed body and a seat body. It has been suggested that the seat body does not bounce forward by braking in the stationary body during braking, but the disadvantage of this is that the curved body can be curved only when the seat body is laid down at a certain angle, and the curved body cannot be curved in the upright state. When these safety seats are used, they cannot observe the front, and if they are erected for forward acuity, the center of gravity is located at the upper front side, which is more dangerous.

All. Summary of the Solution of the Invention.

Therefore, the present invention solves the conventional problem by enabling the curved movement immediately upon sudden braking even in a state in which the sheet body capable of the curved movement is upright.

Description

Seat safety for infants with curved seats {A car safty seat for a young child}

The present invention relates to a child safety seat of a vehicle, and in particular, to ensure safety by the seat body immediately curves without the forward movement during braking.

Infant car safety seats used in the present is to use a separate safety seat that can be filled with seat belts for infants to be connected to the seat belt mounted on the car, so that infants can maintain a certain degree of safety.

However, in case of sudden braking, the safety seat floats on the car seat, so the child car safety seat, which is positioned higher than the car seat by inertia, pops forward in an instant, so the risk of a safety accident is large, so it is only tied to the infant. Since it was used as a concept, many problems were exposed to practical use for safety.

Therefore, in recent years, it has been proposed that the seat body does not protrude forward by inducing a curvilinear movement during rapid braking in a stationary body fixed to the vehicle.

However, a disadvantage of this is that the sheet body must lie at a constant angle in order for the sheet body to be curved during rapid braking.

In other words, because the potential energy must be low, it is impossible to use practically because of the inconvenience that the infants should lie down for safety. Also, when the infants are upright to secure visibility, the center of gravity is located on the upper side even when the brakes are weak. The more easily jumped forward, the more problems were exposed to practical safety.

That is, when the seat body is erected to ensure forward visibility while ensuring the safety while performing the curved movement, the center of gravity is located above the conventional one, so that the seat body does not immediately curve during rapid braking. It is more dangerous than that.

Therefore, the present invention is to achieve the safety of the function by preventing the instantaneous protruding forward while the seat body is capable of curve movement immediately when sudden braking occurs even in a state where the curved body moves upright.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figure 1 and 2, the present invention is coupled to the fixing body 10 having a fixing means which can be supported on the vehicle bottom surface while being placed on the vehicle seat, by the coupling means up and down the opening of the fixing body. The first and second movable bodies 20a and 20b and the guide member 23 of the first movable body 20a are configured to have a curved sheet body 30 which is curved.

At this time, the fixing means of the fixing body 10 is formed so that the support bar 18 that can be supported on the bottom surface of the vehicle in front of the folding body, the rear of the fixing body 10 in close contact with the back of the car seat A close contact portion 19 may be formed, and an opening 15 may be formed at the center of the fixed body 10 to allow the first and second movable bodies 20a and 20b to be coupled up and down by a coupling means. In the front of the opening 15, the first and second receiving bodies 11 and the first and second movable bodies 20a and 20b, in which the elastic means 12 may be accommodated, are coupled to the opening 15 and rotated back and forth. And a curved support part 16 for stably placing the second movable bodies 20a and 20b on the fixed body 10.

In this case, the elastic means 12 can be accommodated in the connecting table 18a formed at the front end of the support bar 18, as shown in FIG.

In addition, the elastic means 12, which is accommodated in the receiving groove 11 of the fixed body 10 and intermittently moved forward and backward of the first and second movable bodies 20a and 20b coupled by the coupling means, has a spring body therein. The locking projections 17 are formed in the outer front of the inward groove 13 and the inward groove 13 into which the 14 is inserted.

In addition, the coupling means in which the first and second moving bodies 20a and 20b, in which the front and rear movements are interrupted by the elastic means 12, is coupled to the opening 15 of the fixed body 10, passes through the opening 15. Coupled to the coupling bolt 50, the coupling bolt 50 is inserted through the through holes (21a, 21b) formed in the first and second movable bodies (20a, 20b), the through holes (21a, The front and rear intervals of 21b) are formed to be narrower than the width before and after the opening 15 of the opening 15 of the fixture 10, so that the first and second movable bodies 20a and 20b move forward and backward from the fixture 10. It is done.

At this time, the first and the second movable body is always retracted by the elastic force of the spring body 14 of the elastic means 12, and the first and the second movable body (20a, 20b) with the stationary body 10 Coupling is to be in close contact with each other by the curved support portion 16, this close contact is the safety seat by rotating the first and second movable body (20a, 20b) 180 degrees as shown in FIG. It is possible to selectively the sheet body 30 of the front view and the rear view.

At this time, the front end of the second movable body (20b) is formed as a support protrusion 22 to engage with the engaging protrusion 17 of the elastic means 12 so that the close contact is made without distortion when moving.

In addition, such close closeness allows the first and second movable bodies 20a and 20b to be elastically supported by the elastic means 12 to the younger children who are rearward, and thus plays a role of shock absorbing to some extent. It is to provide comfort to the infants sitting in).

In addition, the guide rail 31 of the curved sheet body 30 coupled to the upper side of the first movable body 20a is coupled to the curved sheet body 30 so as not to be separated by the locking end 24 of the guide unit 23. Flexible curved motion is generated by the guide rail 31 of the c), and the fixing of the upright angle of the curved sheet body 30 is perforated to penetrate to the side of the guide rail 31 of the curved sheet body 30. The guide pin hole 32 is aligned with the fixing pin hole 26 formed in front of the first movable body 20a, and then fixed by sandwiching the pin 27 laterally. It may be in a perforated form or in a separate form.

When sudden braking occurs in the fixed state as described above, the first and second moving bodies 20a and 20b are moved forward by inertia, thereby preventing the curved sheet body from protruding forward. As the pins are lowered into a broken shape, the pins 27 are broken and are immediately curved.

At this time, the rear side of the curved sheet body 30 imparts a buffering force to return while preventing further progression when moving forward by the elastic body 36 connected to the first movable body 20a, and at the same time, such an elastic body ( By the restoring force of 36), the return of the curved sheet body can be made completely and easily.

Therefore, even when the curved sheet body 30 having the curved motion is upright, the first and second moving bodies 20a and 20b are fixed back and forth by the coupling bolt 50 at the opening 15 of the fixed body 10 at the time of sudden braking. Since the width of the opening is wide in the fixed state to have a width, the first and second moving bodies, which are movably coupled in the opening 15 and coupled with the coupling bolts at the time of sudden braking, are primarily provided by the width of the margin of the opening 15. By moving forward, the curved sheet body is pulled down so that the curved sheet body 30 is not easily moved forward and is immediately curved.

In addition, when the curved sheet body 30 to be curved is started or the curved movement is started, the guide groove 32 is formed on the inner side of the guide rail 31 to prevent the curved sheet body from being lifted upward. The auxiliary guide rail 33 is attached to the upper surface of the first movable body by a fastening means by screws or the like, and has a fixing plate 34 having a locking protrusion 34a so as to be caught by the guide groove 32. It is to prevent the guide rail 31 from being separated from the locking end (23a) of the guide portion 23 when the curved sheet body is bent by fixing firmly mounted or fixed by bolts or the like.

At this time, the fixing plate 34 is to form a coupling protrusion 35, the upper surface of the first movable body 20a to form a coupling recess 25 to be able to enhance the coupling fixing force of the fixing plate 34.

In this case, as shown in FIG. 4, the fixing plate 34 forms a fixing means 37 for fixing the elastic body 36 so that the elastic body 36 having one end connected to the rear of the curved sheet body 30 may be formed. Fixing for connecting to the movable body 20a can be made easy.

In addition, the upright angle of the curved sheet body 30 is fixed to the upper portion of the pin lifting hole 41 in front of the first movable body 20a, as shown in FIGS. The substrate 40, which is mounted to be protruded into the protrusion, is fixed by fastening means using screws or bolts, and then slides by engaging the slide body 43 to be inserted into the groove portion 42 of the substrate 40 to be slid back and forth. When the sieve 43 moves forward and backward, the curved sheet body 30 is moved up and down as shown in FIG. 15 by moving the pin 27 fitted into the slide groove 41a of the pin hatch 41 by the vertical groove 44. As the pin 27 is coupled to the hook groove 38 of the hook body 37 formed at the front lower end of the upright angle, it is possible to fix the upright angle.

In addition, when the safety seat is connected to the seat belt 100 of the car seat, the safety of the seat belt 100 is pulled by the release length of the seat belt due to the interval of time that the pull belt is released while the seat belt is released. At the same time, the bottom is fixed to the bottom surface of the fixing body 10 by means of screws or bolts in order to prevent the safety seat from jumping forward and to prevent it from bouncing to the upper side of the curved sheet body 30 generated during a collision. A folding bar 52 corresponding to the pull bar 53 and the pull bar 53 which are pulled by the folding means 52 and the folding means 52 mounted on the side of the sieve 51 and the bottom body 54. And the hanger bar 54 is fitted at the bottom surface of the fixture 10 to expose the upper portion of the U-shaped bolt 55 exposed to the upper portion of the guide portion 23 of the first movable body as shown in FIG. Tighten nut 56 is inserted into both ends exposed. Lim will ever be.

At this time, the pull bar 53 is made of a wire, and the lever 53b folded by the hinge 53a is formed to protrude one side of the guide plate to be folded and coupled to the hinge formed by bending. , The pulling of the pull bar is induced by the shaft portion 53c along the shanghai of the lever.

At this time, if possible, the shaft portion 53c is located at the rear of the hinge 53b to lengthen the pulling distance of the pull bar 53 by the lever.

In addition, as a hook method for pulling the pull bar, the hook portion 54a is formed on one side of the hook bar 54, thereby enabling a strong fixing by the hook of the pull bar.

In addition, a pair of guide plates 57 protruding upwardly orthogonally to the bottom 51 in the state of tightening and the pressure bar 58 that is in close contact with the expansion portion 57a of the guide plate is a pressure bar ( On one side of the 58 is inclined surface (58a) is formed to be in close contact with the expansion pipe (57a) and the pressure bar (58) in the cutout portion 59 of the bottom 51 as shown in Figure 12 60) is supported by the elasticity is to flow from side to side.

At this time, the pressure bar 58 is formed so as to integrally form the clamping groove 58b at the lower end of the pressure bar so as to prevent the upper side from being moved left and right or from the incision 59 by a separate screw or welding. This is to prevent a variety of known methods are used.

Therefore, for use, the seat belt is inserted into the guide plate in an overlapped state, and then the seated seat belt overlaps with the pressure bar. When the pull bar is pressed against the expansion part of the guide plate, the seat belt is pulled by the inclined surface of the pressure bar. In this state, the pulling bar is hooked to the hooking portion 54a of the hook bar, and then the lever is pulled to fix the hook bar firmly.

After the infant is seated on the seat body to adjust the seat body up and down to ensure the visibility of the infant and then pin the pinhole of the seat body through the fixing pin hole 26 to maintain a constant angle of the seat body upright .

In that state is to fasten the infant using the seat belt of the seat.

In this state, during the sudden braking or collision, the first and second moving bodies are moved forward by inertia, and at the same time, the first moving body and the sheet body are integrally formed by the pins. Since only a certain distance is to be moved horizontally, the curved sheet body pulled down will bend the pin by the force to continue to move while the curved movement.

At this time, the locking end of the guide part of the first moving body and the fastening nut by the hook bar by the U-shaped bolt and by the strong pull fixation by the pull bar of the hook bar, or by engaging the guide groove by the auxiliary guide rail by the locking protrusion of the fixing plate By this, the curved sheet body will be flexibly curved by being offset by the upward force.

In addition, the force to jump forward is also a bending movement without any movement because the seat belt 100 is strongly adhered by the inclined surface to the expansion portion of the guide plate by the pressure bar so that the pulling gap does not occur.

As described above, the present invention is to maintain the safety of the infant because the curved sheet can be completely curved movement immediately even when the braking sheet body is upright, even during rapid braking by the movement of the moving body.
