Description

CHILD HOLDING DEVICE

A child restraint is a passive safety device for children from 4 years old (estimated height from 110 cm) used in vehicles. In particular, it concerns the design of the device, which is used in conjunction with the standard seat belts with fastening at three points. State of the art

In the prior art, special restraint devices are known for children from 4 years old, which, together with standard three-point seat belts, having a waist and shoulder belts, were used to remove a diagonally elongated shoulder harness from the child’s face and neck. The known devices have a complex structure, therefore, have not found wide application (see Canadian patents 2310865 from 10/14/1999, US 0033102 from 10/25/2001).

The closest in technical essence and the achieved result is a child restraint (shoulder strap adjuster for car seatbelts). The known device is used in conjunction with the standard seat belts with fastening at three points. The known device comprises a housing of a pair of facing each other panels, permanently connected in the central part and forming two channels outside the central part for passage, respectively, of the waist and shoulder harnesses. The known device further includes fastening means (Velcro fasteners) located along two lines forming the outer edges of the panels and overlapping each channel of the corresponding belt. Both panels are generally triangular or diamond-shaped, and both channels converge in the direction from the trailing edge to its leading edge. The panels are made of hard material with shock absorbers or reinforced

SUBSTITUTE SHEET (RULE 26) cushioning material (see patent GB 2349364 of 04/26/1999, patent EP 1048535 published date 02.11.2000).

The known holding device is well suited for its intended use. The child is held in extreme situations by regular seat belts by maintaining the direction of the diagonally elongated seat belt through the middle of the shoulder, eliminating his sliding to the child’s face or neck. However, the known device does not provide measures to prevent the housing of the holding device from slipping along the belts, which may reduce its reliability and safety for the child in particularly difficult traffic situations. The known design is also not reliable due to the fact that detachable fastening means located along the edges of the housing and experiencing in extreme situations an increased load from the pressure of the belts can be unfastened. In addition, due to the asymmetric shape when changing the right seat to the left housing of the known device must be rotated 180 degrees around a vertical axis. As a result, both panels, pressing to the body with either the front or the back side, work to bend either one or the other side, which leads to quick wear of the product, loss of shape and presentation. Disclosure of invention

The basis of the invention is the task of improving the safety, ease of use and efficiency of the device.

The technical result of increasing safety and ease of use is achieved by increasing the reliability of fixing the device on the seat belts and reducing the load on the detachable fastening means due to their transfer from the edge to the center of the case. Due to the symmetrical shape of the case, which allows changing the front side when changing the right seat to the left, the presentation and the service life are improved. Single panel execution is more cost-effective

SUBSTITUTE SHEET (RULE 26) more technologically advanced material, which reduces the final cost of production. The proposed child restraint is used in conjunction with the standard seat belts with three-point fastening, including waist and shoulder belts. The device comprises a central part of the housing with two channels at the edges for the waist and shoulder belts and detachable fastening means overlapping each channel of the corresponding belt. The channels converge in the direction from the trailing edge of the housing to the front. According to the invention, the housing is made in the form of a single panel, the edges of which are bent along the fold line and fastened to the central part of the panel, forming channels for laying the seat belts. The inner surface of the channels is made with a high coefficient of friction. In the inventive device, the panel is made symmetrical. The fold lines of the panel are made parallel to the side edges at a distance of not less than the width of the seat belts (+ additional). In an optimal embodiment of the device, the panel in closed form is generally trapezoidal, but may also have another symmetrical shape. For an embodiment of a fabric panel with shock absorbing filler, detachable fastening means are fasteners on buttons / buttons / Velcro tape / Zipper tape. For an embodiment of a panel of polymeric material, detachable fastening means are button fasteners / buttons / rotary locks.

In FIG. 1 is a drawing of a prototype device consisting of two identical panels 1. Panels 1 are made of fabric with shock absorbing filler, sewn together in the center along line 2, and detachably connected at the edges with a Velcro tape. The inventive child restraint device according to figure 2, 3 is made in the form of a single symmetrical panel 4 of hardened material, for example, from a dense fabric with shock absorbing filler. Buttons / buttons 5 are fixed along the edges of the panel 4, the counterparts 6 of which are located on the central part so that when fastening them along the edges of the device, channels 7.8 are formed for putting in them standard waist 9 and shoulder 10 safety belts. Since the design is symmetrical, when changing the right seat to the left, the channels for the waist and shoulder seat belts are interchanged by turning the case clockwise (or counterclockwise). Due to this, the front side of the body always remains the front. For easy bending

SUBSTITUTE SHEET (RULE 26) the filler is made of two layers. One layer is continuous, for example, of foam, the second layer, for example, of isolon foam, is interrupted on the bend lines 11, so the thickness of the filler on the bend lines is less. The device according to Fig. 4,5 differs from the previous one by a change in the means of fastening to the Velcro tape. The tape "loop" 12 is fixed on the Central part, and the tape "hooks" 13 - at the edges (or vice versa). The device of FIG. 6,7 differs from the previous two by changing the means of fastening to the tape "lightning" 14. On Fig.9 shows a device in which the panel 15 is made of polymeric materials. Changing the shape of the panel 15 in FIG. 10.11 due to the saving of polymer material. In FIG. 12 - the inventive device is made of a polymeric material in which the panel 15 is molded immediately with the edges 16 bent toward the panel, which ensures tight tightening of the seat belts when fastening the edges to the central part. The fold lines on the panel 15 are formed by reducing the thickness of the polymer material along them. For all fabric options, buttons / buttons / Velcro ribbons / zipper ribbons can be used as detachable fasteners, buttons / buttons / rotary locks for all polymer options. FIGS. 13-14 illustrate options for detachable fastening means; FIG. 13 - loop 17 with a button 18, cast at the same time with the panel 15 (or made of another material and riveted), in FIG. 14 is a variant of a loop 19 with a riveted button 20 (or cast along with the panel 15). In FIG. 15-16 show options for the rotary locks 21, 22. For FIG. 2-7 (fabric options) it is practical to make the inner layer of the entire panel of rubberized fabric, for example, of taffeta fabric 190T PU R / Stor, with a rubberized layer to the outside. For FIG. 8-12 (options from a polymeric material) it is practical only to form a “shagreen” surface from the inside of the channels.

The work of the proposed child restraint involves

SUBSTITUTE SHEET (RULE 26) following the instructions for use of this product. The child is seated tightly with his back to the back of the chair. Fasten your seat belt. Having unfastened the fastening means (buttons / Velcro tape / zipper / rotary locks), we put the belt 9 and shoulder 10 belts into the corresponding channels 7.8 of the device, making sure that the belts do not twist. Fastening the channels 7.8, we tighten the shoulder strap 10 so that it passes through the middle of the child’s shoulder and does not have slackness. The waist part of the body should lie at the level of the hips, but not higher than the child’s belt. When changing the right seat to the left body of the device, turn clockwise (or counterclockwise) arrow without changing facial The child is ready for the trip. Due to the increased coefficient of friction on the inner side of the channels 7.8 and the reduction of pressure on the detachable fastening devices, the device is tightly held in its original position and will not allow the shoulder strap to move towards the neck or face during any shocks in vehicles. thereby ensuring travel safety for the child.

Compared with the prototype of the inventive child restraint device has the following advantages. Since the inner surface of the channels is made with a high coefficient of friction, and the detachable fastening means are moved from the edge to the center, the quality of the operational characteristics, namely safety and ease of use, due to the reliability of fixing the device on standard seat belts and reducing the pressure on the detachable fastening means rises sharply, which is very important for the child. In addition, the implementation of one panel, sewn from fabric or cast on injection molding machines, is more technologically advanced and more economical in terms of material consumption, which results in cheaper products. The symmetrical shape of the case allows the product to retain its presentation and life for a long time.
