Detailed Description

The present invention will be described in further detail with reference to the following examples and drawings.

Example 1

As shown in fig. 1, the embodiment 1 of the present invention provides a head and neck protection safety belt, which includes a first safety belt 1 for fixing the trunk and a second safety belt 2 for fixing the mandible, and the second safety belt 2 and the first safety belt 1 can be synchronously stretched and contracted in the same amplitude, so that when emergency braking, the head and neck and the body can swing in the same direction and in the same amplitude under inertia, thereby avoiding whip damage to the neck.

In a specific arrangement mode, the first safety belt 1 comprises a first belt body 11, a first winding device 12 and a first belt buckle 13 which are respectively arranged at two sides of the seat 4, a first hanging ring 14 is arranged at the same side of the headrest part 5 of the seat 4, which is located at the first winding device 12, one end of the first belt body 11 is fixed in the first winding device 12, the other end of the first belt body passes through the first hanging ring 14 and is fixed on a vehicle body at one side of the first winding device 12, and a first locking tongue 15 matched with the first belt buckle 13 is arranged on the first belt body 11; the second safety belt 2 comprises a second strap body 201, a second hanging ring 202, a third hanging ring 203 and a second buckle 204, the second hanging ring 202 is arranged on one side far away from the first hanging ring 14, the second hanging ring 202 and the third hanging ring 203 are symmetrically arranged on two sides of a headrest portion 5 of the seat 4, the second buckle 204 is arranged on the first strap body 11 and close to the first hanging ring 14, one end of the second strap body 201 is provided with a second bolt 205 matched with the second buckle 204, the other end of the second strap body sequentially penetrates through the third hanging ring 203 and the second hanging ring 202 and is fixed in the third hanging ring 203, and a lower jaw fixing portion 206 is arranged on the second strap body 201 and located between the second hanging ring 202 and the third hanging ring 203.

In an actual vehicle, the first safety belt 1 is an existing three-point safety belt, and is different in that a second safety belt 2 for fixing a head and neck is added to the headrest portion 5. When the vehicle is running on the expressway, the passenger puts the chin fixing part 206 of the second seat belt 2 around the chin and inserts the second latch tongue 205 into the second buckle 204 to fix the head; when a special condition (for example, a front obstacle or other vehicles or a vehicle has a fault) needs emergency braking, the body of a passenger tilts forwards under the action of inertia, at the moment, the first safety belt 1 fixes and buffers the body of the passenger, meanwhile, the first belt body 11 stretches to a certain extent along with the forward tilting of the body of the passenger, and as one end of the second safety belt 2 is fixed on the first belt body 11 and connected with one end of the first coiler 12, the second belt body 201 can also stretch when the body of the passenger tilts forwards, and the stretching amplitude is the same as that of the first belt body 11, at the moment, the neck of the passenger can be prevented from swinging forwards, and the head and neck of the passenger can be prevented from moving forwards by matching with the inertia of the head; when the rear-end collision happens, the body of the passenger can fall backwards under the action of inertia, and the head of the passenger cannot be thrown backwards greatly due to the fixing action of the second safety belt 2, so that the head is prevented from impacting the headrest part 5 backwards to cause injury. Since the second seatbelt 2 is fixed by the retractor like the first seatbelt 1, the second seatbelt can be pulled gently to be appropriately loosened even when the posture needs to be adjusted, so that the cervical spine stiffness caused by the long-time close contact with the headrest portion can be avoided.

The neck protection safety belt that this embodiment provided simple structure, low cost, through the flexible of the first safety belt of same coiler simultaneous control and second safety belt, can protect passenger's truck and neck portion simultaneously, can restrict the range of each position inertial motion more than the passenger waist with the same range under the circumstances such as emergency brake, can not cause too big resistance to the head and neck portion simultaneously, can effectively avoid too big inertia to cause whip appearance damage to the cervical vertebra from this. The safety belt is suitable for vehicles with high running frequency and more mileage on a highway, and can effectively reduce the probability of head and neck injury caused by a highway accident when being widely applied.

Example 2

As shown in fig. 2, the present embodiment 2 provides a head and neck protection safety belt based on embodiment 1, and embodiment 2 further defines that a protection pad 207 is disposed on the mandible fixing portion 206, so as to prevent wear to the mandible skin caused by long-term use, improve the wearing comfort, and reduce the psychological conflict of the passenger wearing the second safety belt 2.

The top of the headrest portion 5 can be further provided with a clip 3 for fixing the second belt body 201, when the vehicle runs at a low speed on a common road and the passenger does not need to use the second safety belt 2, the clip 3 can be used for fixing the second belt body 201 on the top of the headrest portion 5, so that the situation that the second belt body 2 which is suspended is uncomfortable for the passenger is avoided.

Example 3

As shown in fig. 3, this embodiment 3 provides a head and neck protection safety belt based on embodiment 1, and this embodiment 3 further defines that an insertion groove 208 is provided in the second buckle 204, a plurality of saw-toothed first protrusions 209 are formed on the side wall of the insertion groove 208, and second protrusions 210 with elasticity and adapted to the first protrusions 209 are formed on the two side edges of the second lock tongue 205.

When the second safety belt 2 prevents the head and neck of the passenger from swinging forwards, the second belt body 201 inevitably exerts a resistance force on the head of the passenger; when the automobile is braked to run at an excessively high speed or the automobile is braked to an excessively high speed, the inertia of the human body is excessively large, the resistance of the safety belt is also excessively large, and at the moment, if the automobile is braked suddenly or the rear-end collision occurs, the neck is also injured by strong inertia, so that the second safety belt 2 is required to be further matched with the inertial motion of the head and neck besides the stretching of the second belt body 201 to a certain degree. The sawtooth-shaped first protrusion 209 in the slot 208 can play a certain blocking role for the second lock tongue 205, so that the second lock tongue 205 can be gradually pulled out when receiving a large pulling force, the connection stability of the second safety belt 2 can be ensured, the stretching range of the second safety belt 2 can be further expanded, the resistance applied by the second safety belt 2 to the head of a passenger is reduced, and unnecessary injury to the head and the neck is avoided. Even if the second locking tongue 205 is completely separated from the second buckle 204, sufficient buffering time can be provided, so that the injury to the head and neck of the passenger can be effectively reduced.

In order to further improve the stability of connection, two rows of first protrusions 209 arranged oppositely are formed on the side wall of the slot 208, and the second protrusion 210 is matched with the groove between any two adjacent first protrusions 209, so that the two sides of the second protrusion 210 are simultaneously subjected to the resistance of the first protrusions 209 during stretching, and the second lock tongue 205 is prevented from being separated from the second buckle 204 during stretching.

The second lock tongue 205 and the bottom of the slot 208 can be connected through an elastic rope 211 to prevent the second lock tongue 205 from being thrown out under violent pulling and causing injury to passengers.
