However, this design still cannot provide sufficient rigidity at the middle and rear position of the seat; Chinese patent literature (announcement date: 2011.07.06, announcement number: CN 201890166U) discloses an anti-submersion mechanism, which consists of a car seat Cushion frame, reinforcement rods and steel wires used to form the seat basin
This mechanism raises the reinforcing bar at the front of the seat together with the seat pan steel wire to increase the support for the occupant's hip in the longitudinal direction, but the improvement is limited
In addition, this design requires a strong actuating device to realize the lifting of the reinforcing bar and the steel wire of the seat pan, thus increasing the quality of the seat, which is not conducive to the lightweight of the vehicle

Embodiment Construction
[0029] The present invention will be further described below in conjunction with accompanying drawing of description:
[0030] as attached Figure 1~8 As shown, a safe and comfortable car seat for preventing diving includes a seat back, a seat pan frame 1, a seat cushion and an anti-submersion mechanism arranged on the seat pan frame 1, and the seat pan frame 1 includes a seat pan frame body 101 and respectively The fixing bases 102 are fixedly arranged on both sides of the seat pan frame body 101 .
[0031] The anti-submersion mechanism includes connectors 4 respectively arranged on both sides of the seat pan frame 1, a connecting belt 2 located under the seat cushion and connected to the connectors 4 on both sides at both ends, and at least one of the connectors 4 on both sides 4 is rotatably arranged and is used for winding or releasing the connecting strap 2 . The anti-submersion mechanism also includes a control mechanism for controlling the rotation of the connecting p...

The invention relates to a safe and comfortable automobile seat preventing sinking. The safe and comfortable automobile seat is provided with a sinking preventing mechanism which comprises connecting pieces arranged on the two sides of a seat pot framework respectively, and a connecting belt located below a cushion, wherein the two ends of the connecting belt are connected with the connecting pieces on the two sides respectively. At least one connecting piece on one side of the connecting pieces on the two sides can be rotationally arranged and be used for winding or releasing the connecting belt. The sinking preventing mechanism further comprises a control mechanism, the connecting belt has a non-working state and a working state, when the connecting belt is in the non-working state, part of the connecting belt is wound on the connecting pieces under the action of the control mechanism, when the connecting belt is in the working state, whole connecting belt or part of the connecting belt wound on the connecting pieces can be pulled out under the action of external force, the control mechanism has the locking function and can prevent the connecting belt from being further pulled out in necessity, so that the rigidity of the cushion is improved, and a passenger is prevented from sinking. The sinking preventing mechanism of the automobile seat is simple in structure, flexible in arrangement and small in added mass and cannot affect the comfort of the seat when the passenger normally takes an automobile.
Description
technical field [0001] The invention belongs to the field of automobile safety occupant protection, is mainly used in industries such as automobiles, and in particular relates to a safe and comfortable automobile seat for preventing diving. Background technique [0002] When the car has a frontal collision, the occupant will move forward under the action of inertia, and under the action of restraint systems such as seat belts, the occupant will also move downward to compress the seat cushion. This movement has an adverse effect on occupant protection - causing the belly strap of the seat belt to move upward relative to the hip, and in the worst case, causing the belly strap to slide over the front structure of the hip bone and invade the soft tissue of the abdomen, which is harmful to the occupant. The occupant suffers serious injuries, which are often referred to as "dive injuries". At present, the existing technology measures to prevent the occupant from diving is mainly ...
