Description

Technical Field

[0001] The invention belongs to the technical field of lightning protection seats, in particular to an adjustable lightning protection seat footrest with an energy absorption device. Background Art

[0002] Military vehicles are very vulnerable to the threat of mines and improvised explosive devices (IEDs) during driving. As an effective occupant protection device, mine-proof seats are currently widely used in mine-proof vehicles. Mine-proof seats for passengers are generally equipped with footrests to prevent direct contact between the occupants' lower limbs and the floor, thereby greatly reducing the damage to the occupants' lower limbs caused by the blast wave. However, most mine-proof seat footrests are not equipped with a restraint system. After being hit by the blast, the occupants' lower limbs are very likely to collide with each other or with the structure inside the car, causing secondary injuries to the occupants.

[0003] Chinese patent publication number CN112393642A discloses an anti-impact foot safety restraint device, including a seat, a pedal mechanism, and a foot restraint belt. The restraint device can ensure that the lower limbs of the person are always fixed on the pedal mechanism, isolating the impact of the floor from being transmitted to the lower limbs of the person. However, the foot safety device does not have an energy absorption device and the pedal mechanism and the foot restraint belt cannot be adjusted, so it is difficult to take into account the safety and comfort of the lower limbs of the occupant. Therefore, there is room for improvement in the above-mentioned problem. Summary of the invention
