This application discloses a head-mounted neck and shoulder restraint device, relating to the field of medical protective equipment technology. It includes a helmet, face protector, neck protector, and shoulder pads. The face protector is rotatably mounted on the front side of the helmet. The helmet, from the outside in, comprises a hard leather outer layer, an engineering mesh plastic shell middle layer, and a breathable sponge inner layer. The neck protector is fixed to the helmet and tightened with Velcro. The shoulder pads are located on both sides of the helmet and are equipped with straps. This application utilizes the helmet to cushion and protect the head of agitated mental patients who may bump their heads, preventing head injuries. Simultaneously, the face protector, neck protector, and shoulder pads prevent patients from biting themselves or others, thus effectively restraining the patient while protecting both the patient and others from harm.

This invention provides a head and neck protection device for rear-end collisions, including a headrest seat, a first buffer assembly, and a limiting mechanism. When a rear-end collision occurs, the impacted vehicle accelerates forward, causing the head of an occupant to strike the first cushion. Upon impact, the first cushion drives a guide seat to move, compressing multiple sets of buffers. At this time, the first cushion and the multiple buffers work together to cushion the impact on the head, improving the device's buffering effect and reducing head injuries. Simultaneously, the movement of the guide seat drives the fixing assembly to release the limiting rod. The driving component then drives the limiting rod to rotate to a second state, so that the arc-shaped portion of the limiting rod faces the first cushion. When the head moves forward due to the impact reaction force, the limiting rod can contact the head, thereby limiting large-scale forward head movement, preventing neck strain, and improving the device's protective effect.

This utility model discloses a compressible engine hood buffer block and a car with pedestrian protection in mind, relating to the field of automotive safety design. It includes: a cylindrical housing comprising an upper housing and a lower housing connected to each other, with a connecting hole at the top of the upper housing; a spring, one end of which is fixed inside the lower housing and positioned along the axial direction of the housing; a buffer block body, the middle of which is disposed through the connecting hole, with one end of the buffer block body outside the housing for connection to the engine hood, and the other end of the buffer block body inside the housing engaging with the inner wall of the upper housing; and a support block disposed inside the housing, with both ends connected to the spring and the buffer block body, respectively. When the engine hood with the buffer block installed is normally closed, after a pedestrian collision, the buffer block body is compressed and retracted into the housing after being subjected to the impact force, causing the engine hood to shift downwards a certain distance, creating a larger energy absorption space for head impacts and reducing head injury.
