Technical Field

[0001] This utility model belongs to the field of military seat technology, specifically referring to a wall-mounted, inclined, energy-absorbing, and lightning-resistant seat. Background Technology

[0002] In modern military operations, military vehicles face threats including landmine explosions, which generate massive shockwaves that transmit intense impacts through the vehicle's chassis to the internal structure. This impact can cause severe spinal compression injuries or traumatic brain injuries to the occupants. Therefore, military vehicles are often equipped with mine protection devices to ensure occupant safety.

[0003] Current lightning protection technologies used in military vehicles employ several methods. One approach involves installing shock-resistant suspension on one side of the tires; another is incorporating energy-absorbing devices in the vehicle body to absorb blast impacts. However, regardless of the method, a significant amount of energy is still transferred to the seating area that comes into contact with the occupants, posing a certain degree of danger. Furthermore, military seats, while providing lightning protection, also need to be portable, allowing for quick folding during combat to improve operational efficiency. Utility Model Content
