Detailed description of the invention
Refer to Fig. 1, the schematic diagram of the child safety seat 10 that Fig. 1 is first embodiment of the invention.Child safety seat 10 comprises backboard 12, head rest 14 and safety strap 16.Head rest 14 is arranged on backboard 12, and backboard 12 moves up and down relatively.Between head rest 14 and backboard 12, having space I can pass through for safety strap 16, and space I is the front Hou pitch difference of head rest 14 and backboard 12.The part belt body (not being shown in figure) of safety strap 16 is positioned at the rear of backboard 12, and another part belt body is positioned at the front of backboard 12.In other words, safety strap 16 is arranged between backboard 12 and head rest 14, safety strap 16 can (not be shown in figure by reel releasing mechanism, conventionally be arranged on backboard 12 rears) elongate or shorten according to user's demand, make child safety seat 10 be adapted to the occupant (infant) of different height and build.Preferably, head rest 14 is movably arranged on backboard 12.When head rest 14 moves to adjust the height of head rest 14 with respect to backboard 12, the length of child safety seat that safety strap 16 is revealed in 10 front sides can be covered by head rest 14 and automatically produce corresponding length variations.
As shown in Figure 1, head rest 14 has inclined conducting 18, be arranged on the downside (for example position of lower edge) of head rest 14, and inclined conducting 18 is towards top indent.Backboard 12 has opening 20, is arranged on backboard 12 proximity heads and leans on 14 upper end.Opening 20 can pass through for safety strap 16, allows safety strap 16 traverse to another opposite side (front side) of backboard 12 from a side (rear side) of backboard 12.In the time that the relative backboard 12 of head rest 14 moves down to reduce the height of head rest 14, safety strap 16 can slide along inclined conducting 18, and inclined conducting 18 applies pressure to safety strap 16, makes safety strap 16 produce shifted laterally along the plane of structure of inclined conducting 18.
In the first embodiment, inclined conducting 18 is a kind of arcuate structures.The height of arcuate structure two side ends 181 is lower than the height of arcuate structure centre portion 183, and meaning is that inclined conducting 18 is concave inward structure towards the top of child safety seat 10.Refer to Fig. 2, the child safety seat 10 that Fig. 2 is first embodiment of the invention is at the schematic diagram of another operation mode.When head rest 14 touch-safe band 16 slidably, inclined conducting 18 can drive safety strap 16 toward head rest 14 center (meaning is toward the centre portion 183 of inclined conducting 18) draw close, as shown in Figure 2.Centre portion 183 can be shifted to from the two side ends 181 of arc inclined conducting 18 respectively in two upper ends 161 at safety strap 16, make two upper ends 161 close up close, the spacing of two upper ends 161 can be along with safety strap 16 shift-in and shortening under inclined conducting 18, contribute to the occupant's that complete coated stature is less shoulder, the binding force of intensified safety band 16 to occupant.
Refer to Fig. 3, the schematic diagram of the child safety seat 10 ' that Fig. 3 is second embodiment of the invention.In a second embodiment, the assembly with the first embodiment with identical numbering has identical structure and function, is not repeated.Child safety seat 10 ' comprises backboard 12, head rest 14 and safety strap 16.The difference of the second embodiment and the first embodiment exists: the inclined conducting 18 ' of head rest 14 is structures of a kind of tool turnover angle.Inclined conducting 18 ' comprises the first surface 185 that is connected and second 187.First surface 185 and second 187 alternative are designed to plane or cambered surface, determine according to design requirement.Between first surface 185 and second 187, present angle theta.The numerical value of angle theta is less than 180 degree, and meaning is that inclined conducting 18 ' is concave inward structure towards the top of child safety seat 10 '.Wherein, the height at inclined conducting 18 ' two ends is lower than the height in inclined conducting 18 ' stage casing.
Refer to Fig. 3 and Fig. 4, the child safety seat 10 ' that Fig. 4 is second embodiment of the invention is at the schematic diagram of another operation mode.In the process of height of adjusting head rest 14, user moves down head rest 14, the lower end of head rest 14 applies pressure to safety strap 16, safety strap 16 slides and draws close toward head rest 14 center along the plane of structure of inclined conducting 18 ', make two upper ends 161 of safety strap 16 move on to the position of the angle theta in indent district, as shown in Figure 4.So, inclined conducting 18 ' just can shorten the spacing of two upper ends 161 of safety strap 16, and the capable of preventing shoulder parts anti-avulsion that makes safety strap 16 can more press close to occupant falls.
In sum, child safety seat of the present invention arranges inclined conducting in the lower end of the contiguous backboard of head rest, and inclined conducting has indent, and indent is towards the top depression of child safety seat.While thering is no occupant, safety strap can not contact at head rest vertically downward.When on child safety seat described in occupant and while buckling safety strap, because shoulder provides width spacing, (for example thoracic cavity thickness) makes safety strap support head rest, allow safety strap slidably contact head lean on.When head rest moves down with respect to safety strap, the indent of inclined conducting can be drawn two upper ends (shoulder belt section) of safety strap and be moved toward head rest center from the left and right sides of head rest respectively, and meaning is that the shoulder belt section of safety strap can be drawn close each other.Because head rest can cause and send out the start that safety strap is drawn close to center along inclined conducting relative to moving of backboard, therefore it is less to work as occupant's build, head rest downwards miles of relative movement is larger, to draw close amplitude corresponding larger at the center of the upper end of safety strap (shoulder belt section), contributes to be more closely coated occupant's shoulder; Other direction, when occupant's build is larger, the miles of relative movement of head rest is less, and it is corresponding less that amplitude is drawn close at the center of the upper end (shoulder belt section) of safety strap, and the shoulder that safety strap can suitable corresponding occupant, to provide the comfortable safe environment of taking.
Therefore, according to technique scheme, child safety seat of the present invention at least has following advantages and beneficial effect: because inclined conducting has indent district, when safety strap moves along inclined conducting, two shoulder belt sections of safety strap can slide along indent district more each other close, and the spacing of shoulder belt section narrows the shoulder that is coated occupant with fit.In addition, the height of user's capable of regulating head rest, the shoulder belt section of safety strap, changing when headrest height the automatically spacing of corresponding adjustment shoulder belt section, improves binding force and the safety of child safety seat for occupant.
