A kind of child safety seat
Technical field
The present invention relates to a kind of vehicle safety equipment, specifically a kind of child safety seat.
Background technology
Current child safety seat generally all arranges the securing band of five-point type, five-point safety band is provided with three point of fixity in the cushion part of safety seat, current point of fixity is by offering securing band through hole in cushion part, securing band is connected through this through hole with " day word button ", securing band through hole can not be passed due to " day word button " thus play the effect of point of fixity, this kind of fixing mode needs the cushion part at safety seat at least to open three through holes, install to put needs to climb over safety seat simultaneously, installs very inconvenient, in addition for ensureing the reliability that safety seat is fixing, existing safety seat generally arranges ISO-FIX interface arrangement in the both sides of seat bottom, it is provided with pull-up hook device on the top of backrest, upper drag hook comprises securing band, upper drag hook and securing band length-adjustment buckle, securing band one end is fixed on backrest by " day word button ", the other end is connected with securing band length-adjustment buckle, upper drag hook is connected by another section of securing band and securing band length-adjustment buckle, owing to fixing portion and the child safety seat chair back distance of some vehicle and upper drag hook are very near, this kind above adds between drag hook with securing band length-adjustment buckle that one section of securing band being connected has exceeded backrest and the distance in fixing portion at present, thus fixing effect is not had.
Summary of the invention
It is an object of the invention to provide a kind of child safety seat, upper surface in cushion part arranges three securing band fixed grooves, " day word button " is placed in securing band fixed groove, it has been screwed strongback at securing band fixed groove notch place simultaneously, " day word button " is fixed in securing band fixed groove by strongback, thus play the effect of fixing " day word button ", without the need in cushion part perforate after the structure of employing the present invention, also without the need to turnover seat is come when securing band is installed, device is convenient, cushion part has opened the intensity that through hole improves cushion part less simultaneously.
For achieving the above object by the following technical solutions:
A kind of child safety seat, comprise cushion part, back-rest and five-point safety band, cushion part upper surface arranges the compensating roller button of securing band, the position of the corresponding securing band length-adjustment buckle of cushion part has securing band through hole, five-point safety band is comprised two shoulder belts in top and is connected with compensating roller band by connector link, compensating roller band coordinates through buckle compensating roller with securing band of above-mentioned securing band through hole, it is characterized in that: the upper surface in described cushion part also arranges three securing band fixed grooves, three securing band fixed grooves there is one be positioned at side after middle security strip length adjusting button, another two left and right sides being positioned at cushion part,In securing band fixed groove or side screw is set, a strongback is had to be coordinated the notch place being fixed on securing band fixed groove with screw by screw, being provided with guiding ring on strongback, three securing band of five-point safety are connected through guiding ring with " the day word button " being placed in securing band fixed groove.
Described securing band fixed groove side arranges placement groove, also arranges stage portion bottom securing band fixed groove.
Described securing band fixed groove sidewall offers locating slot on corresponding strongback position, leaves the openning that can put into securing band fixed groove for " day word button " when strongback is fixed in locating slot and between placement groove.
The front side of described cushion part bottom surface securing band through hole also arranges securing band automatic winding device, can be connected with securing band automatic winding device from the compensating roller excessively long compensating roller band deducted of the securing band of cushion part upper surface bottom the anterior wraparound of cushion part.
Have inverted U-shaped groove near the position of both sides and top at the described back-rest back side, also two grooves it are provided with near the position of both sides in described cushion part bottom surface, two grooves of cushion part bottom surface are connected with the groove of back-rest both sides, in the accommodating square tube of above-mentioned groove, square tube side direction is L-shaped, rear side direction is inverted U-shaped, has the fixed orifices running through back-rest and cushion part at bottom portion of groove, square tube is fixed in groove through fixed orifices and nut cooperation by screw.
The square tube of described cushion part bottom surface also fixes ISOFIX interface arrangement.
Pull-up hook device also it is provided with on the top at the described back-rest back side, comprise the pull-up hook device stated and comprise connecting band and upper drag hook connector link, connecting band upper end is connected with upper drag hook connector link, upper and lower two pilot holes kept supplying drag hook device and pass it are provided with on the top of back-rest, connecting band from upper pilot hole wear into, pass from lower pilot hole again and it is connected with " day word button ", the accommodating groove of " day word button " it is provided with in the rear side of lower pilot hole, pull-up hook device, when straining, should " day word button " be contained in above-mentioned accommodating groove; Described upper drag hook connector link is wholely set by ribbon setter and upper drag hook.
The present invention changes existing securing band and cushion part is connected and fixed mode, the mode of the strongback that " day word button " is placed securing band fixed groove mating band guiding ring is adopted to fix, this kind of fixing mode decreases the quantity of cushion part perforate, is convenient to the shaping of cushion part and enhances bulk strength, adopt this kind of fixing mode securing band assembling convenient in addition, only need to securing band one end be socketed on " day word button " after strongback guiding ring, then securing band is pulled to make " day word button " enter in securing band fixed groove from the openning between strongback and placement groove, during dismounting, finger stretches into securing band fixed groove from above-mentioned openning, due to securing band fixed groove, can reserve between bottom " day word button " and securing band fixed groove and extend into gap for finger, conveniently " day word button " is taken out, then securing band end is unloaded from " day word button ", installation and removal process is very convenient without the need to being climbed over by child safety seat.
The present invention also arranges securing band automatic winding device bottom cushion part, can automatically be packed up by securing band automatic winding device from the compensating roller securing band deducted of the securing band of cushion part upper surface, one section of securing band is avoided to be exposed on the external so that child safety seat entirety is more attractive in appearance.
The present invention arranges groove inside cushion part and back-rest edge in addition, places a square tube, if delivery tube further enhancing the bulk strength of child safety seat so that safe grade is promoted greatly in groove.
The present invention simultaneously considers that the connector link of existing pull-up hook device and upper drag hook are split structures, between connector link and upper drag hook, distance is excessively long, therefore the connector link of pull-up hook device and upper drag hook are arranged to the upper drag hook connector link of one, drag hook and connector link operation in one connection can be saved like this when producing, save workman's cost, improve efficiency simultaneously.
