The specific embodiment
As shown in Figure 1, a kind of child's automotive seats, comprise seat 1, be arranged on 1 rear portion, described seat backrest 2, be arranged at the guardrail 3 that is used to be blocked in the occupant front side of 1 top, described seat, shown in each accompanying drawing, the guardrail body 4 that described guardrail 3 comprises pedestal, be arranged at described pedestal top and can described relatively pedestal slide along fore-and-aft direction, described pedestal comprises the base body 5 of the left and right sides portion that lays respectively at described guardrail body 4.
As shown in Figure 8, be provided with between the described base body 5 of every side and the described guardrail body 4 when described lockout mechanism and be positioned at and make described guardrail body 4 have under the unlocked position towards driving elastic component 16 away from described backrest 2 tendencys toward sliding.
Be respectively arranged with the lockout mechanism that both is locked in three control positioies between the respective side portion of each described base body 5 and described guardrail body 4.
As accompanying drawing 6, shown in the accompanying drawing 7, described lockout mechanism comprises that an end is fixed on the described guardrail body 4 and the other end has the shell fragment 7 of locking part 6, offer base body 5 three lockholes 8 on both, has the guiding surface of being convenient to withdraw from described lockhole 8 on the described locking part 6, guiding surface does not have diagram, described lockout mechanism has latched position and unlocked position, when described lockout mechanism is positioned under the latched position, described locking part 6 is inserted in the described lockhole 8, when described lockout mechanism is positioned under the unlocked position, described locking part 6 all is separated with all described lockholes 8.
Described lockout mechanism also comprises along fore-and-aft direction and is slidingly arranged in operating parts 9 on the described guardrail body 4, has location division 10 on the described operating parts 9, when described lockout mechanism is positioned under the latched position, the other end of described shell fragment 7 with described locking part 6 is between described location division 10 and described lockhole 8, and described location division 10 is near the other end of described shell fragment 7, when described lockout mechanism in the switching process of latched position and unlocked position, described location division 10 breaks away from the other end of described shell fragment 7, the left and right sides portion of described operating parts 9 has described location division 10 respectively, the described lockout mechanism of each described location division 10 control respective side.
Do not have diagram, be provided with between described operating parts 9 and the described guardrail body 4 and make described location division 10 elastic component of the other end of close described shell fragment 7 stably.
Offer length on the described guardrail body 4 along the guide groove 11 that fore-and-aft direction extends, have locating dowel pin 12 on the described operating parts 9, described locating dowel pin 12 can be inserted in the described guide groove 11 slidably.
