[0028] With reference to Figures 1-4 The utility model provides a kind of novel car safety belt of plug -in type, comprising:

[0029] Roof slide rail 1 is installed along roof longitudinal beam longitudinally, and sliding groove 2 is formed in roof slide rail 1, and locking structure 3 is slidably connected in the inside of sliding groove 2;

[0030] B column locking assembly is embedded in the force receptacle 5 of driver same side B column, and the outer surface of force receptacle 5 is flush with B column interior decoration;

[0031] Shoulder strap 6 is provided with shoulder strap connecting assembly 7 matched with sliding groove 2 and force receptacle 5;

[0032] Seat slide rail 8 is installed along seat framework, and seat slide rail 8 is U-shaped slide rail.

[0033] Floor anchor 9 is installed at the outside floor of the seat, according to the number of floor anchors 9, it is installed at one side of the seat or symmetrically installed at both sides, the installation of the floor anchor 9 adopts fixed connection, or adopts common plug-in type automobile seat plug and automobile seat socket assembly for connection;

[0034] Crotch belt webbing 10 connects the seat slide rail 8 and the floor anchor 9.

[0035] The roof slide rail 1 and the force bearing socket 5 form a longitudinal constraint path through the shoulder belt 6, the seat slide rail 8 and the floor anchor 9 form a transverse constraint path through the crotch belt webbing 10, and the two paths intersect at the driver's abdomen.

[0036] As can be seen from the above design, the roof slide rail 1 is fixed in the roof longitudinal beam by bolts, the sliding groove 2 is flush with the roof interior, the entire safety belt forms adjustable longitudinal and transverse constraint paths through the roof slide rail 1 and the seat slide rail 8, the roof slide rail 1 extends longitudinally along the roof longitudinal beam, allows the shoulder belt connecting assembly 7 to slide and lock, and realizes the position adjustment of the shoulder belt 6; the force bearing socket 5 serves as a fixed fulcrum of the shoulder belt 6, and can form a three-point restraint system (roof slide rail point position → B column point position → floor anchor) together with the floor anchor 9, the U-shaped structure of the seat slide rail 8 connects the floor anchor 9 through the crotch belt webbing 10, forms a transverse constraint around the driver's hip, and the paths intersect at the driver's abdomen, forming an ergonomic constraint topology.

[0037] Specifically, the locking structure 3 includes a wedge-shaped pressing block 12 and a friction plate 13 installed inside the roof slide rail 1, the wedge-shaped pressing block 12 is driven to extrude the inner wall of the sliding groove 2 through the knob 14 to realize locking, and the surface of the friction plate 13 is provided with staggered grooves.

[0038] Specifically, the force bearing socket 5 is a double-layer composite structure, including an outer metal force bearing shell 15 and an inner guide module 16, the guide module 16 is provided with a tapered guide cavity 17, and the opening axis of the tapered guide cavity 17 and the extension direction of the sliding groove 2 form an acute angle.

[0039] In the above scheme, the wedge-shaped block 12 and the knob 14 are connected by thread in the specific implementation, and the side surface of the wedge-shaped block 12 is inclined (the inclined surface has a gap with the main body of the wedge-shaped block 12), and the friction plate 13 is located on the inclined surface structure. At the same time, the part of the knob 14 inserted into the wedge-shaped block 12 is a conical structure. By rotating the handle of the knob 14 to apply torque, the conical head of the knob 14 is moved forward to press the wedge-shaped block 12. At this time, the knob 14 expands the wedge-shaped block 12, so that the friction plate 13 is in contact with and pressed against the inner wall of the sliding groove 2 (the knob 14 rotates → the thread advances → the conical head presses the expansion groove in the wedge-shaped block 12 → the inclined surface of the wedge-shaped block 12 expands radially → the friction plate 13 is pressed against the sliding groove), thereby realizing fixation. The grooves on the surface of the friction plate 13 are consistent with the sliding direction, which ensures the sliding process and increases the friction coefficient. The locking structure 3 of the roof slide rail 1 is adjusted steplessly by the wedge-shaped block 12 and the friction plate 13. When the knob 14 is rotated, the wedge-shaped block 12 moves along the inclined surface and presses the friction plate 13 against the inner wall of the sliding groove 2 to generate friction locking. When impacted, the metal bearing shell 15 can effectively bear the impact load.

[0040] Specifically, the U-shaped structure of the seat slide rail 8 has a preset inclination angle, and the preset inclination angle of the seat slide rail 8 is parallel to the human hip axis, so that the crotch belt webbing 10 can naturally fit the hip curve of the driver.

[0041] Specifically, at least one ball slide 18 is arranged in the seat slide rail 8, and the ball slide 18 is connected to the floor anchor plug 19 through the crotch belt webbing 10.

[0042] In the specific embodiment, the seat slide rail 8 and the ball slide 18 are fixed in position by configuring any suitable slide rail locker assembly. In addition, by installing a suitable socket structure at the additional ball slide 18, a new connection support point between the shoulder belt 6 and the ball slide 18 can be generated, and the point can be adjusted to slide around the seat. When the ball slide 18 slides in the U-shaped rail, the handle of the cam locking mechanism (not shown in the figure) drives the eccentric cam to press against the inner wall of the seat slide rail 8, thereby achieving position fixation. After the floor anchor plug 19 is inserted into the floor anchor 9, the transverse constraint path bypasses the outside of the hip to avoid pressing the abdomen.

[0043] Specifically, the shoulder belt connection assembly 7 includes a sliding block 20, and the sliding block 20 is connected to the shoulder belt plug 4 through the shoulder belt 6. The shoulder belt plug 4 and the bearing socket 5 form an oblique constraint path. In addition, the shoulder belt connection assembly 7 can also be installed at the crotch belt webbing in the same way to facilitate the intersection connection with the shoulder belt.

[0044] Specifically, the shoulder belt plug 4 is any suitable market universal automobile seat plug structure, which is used to adapt to the universal automobile seat socket.

[0045] Specifically, the shoulder strap 6 connects the sliding groove 2 and the force bearing socket 5, and the connection line is obliquely across the driver's shoulder, the seat slide rail 8 and the floor anchor 9 are connected by the crotch belt 10, and the connection line bypasses the outside of the driver's hip, the shoulder strap 6 and the crotch belt 10 are connected by the central lock 11.

[0046] In the embodiment, the shoulder strap plug 4 and the floor anchor plug 19 are compatible with the ISO standard interface; the central lock 11 is a modular structure, and is a universal socket structure matched with the shoulder strap plug 4, and has at least two socket directions and corresponding structures.

[0047] As can be seen from the above design, the slider 20 of the shoulder strap connecting assembly 7 slides along the sliding groove 2, and the shoulder strap plug 4 is connected through the shoulder strap 6, the shoulder strap plug 4 can be inserted into the existing car seat socket and the force bearing socket 5, when the shoulder strap plug 4 is inserted into the force bearing socket 5, the longitudinal path (sliding groove 2→car seat socket / seat slide rail 8→force bearing socket 5) obliquely across the driver's shoulder, the transverse path (seat slide rail 8→floor anchor 9) bypasses the outside of the hip, and the two paths meet at the central lock 11, forming a multi-point constraint.

[0048] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
