Abstract：
Seat belts are considered the reason for seat belt syndrome, which mainly occurs during rapid deceleration in motor vehicle accidents. Seat belt syndrome is characterized by contusion of the front torso, intrathoracic or intraabdominal organ injuries, and spinal thoracic or lumbar chance fractures.
This case study presents a 21-year-old female who was injured by a lap-type seat belt and diagnosed with seat belt syndrome after an airplane landing accident. She underwent surgery for lumbar chance fracture and abdominal injury. We discussed the possible harmful effects of lap seat belts in passenger seats on airplanes.
While an airplane is in a flying position, a lap seat belt functions to protect the passenger from any turbulence. However, during the landing or take-off phase, it may not be enough to fully protect the passenger, especially during sudden deceleration accidents, which cause seat belt injuries and head traumas. Therefore the unique design of a double functional passenger seat belt harness, along with a 3- or 4-point buckle protruding from the shoulder, can serve as a more favorable protective measure in limiting the severity of injury a passenger receives. After the plane has taken off, the diagonal seat belt can then be unlocked, leaving the lap seat belt to remain firmly in place and secured.

摘要：
安全带被认为是安全带综合症的原因，这主要发生在机动车事故的快速减速时。安全带综合征的特征是前躯干挫伤，胸内或腹内器官损伤，和脊柱胸椎或腰椎骨折的机会。
本案例研究介绍了一名21岁的女性，她在飞机着陆事故后被膝式安全带受伤并被诊断为安全带综合症。她因腰椎偶然骨折和腹部受伤而接受了手术。我们讨论了飞机乘客座椅上的安全带可能产生的有害影响。
当飞机处于飞行位置时，膝上安全带的作用是保护乘客免受任何湍流。然而,在着陆或起飞阶段，这可能不足以充分保护乘客，特别是在突然减速事故中，导致安全带受伤和头部受伤。因此独特设计了双功能乘客安全带线束，还有一个从肩膀突出的3点或4点带扣，可以作为限制乘客受伤严重程度的更有利的保护措施。飞机起飞后，然后可以解锁对角安全带，让膝部安全带牢牢地保持在原位并固定。
