Abstract

L'invention concerne un siège éjectable pour un véhicule et un véhicule le comprenant. Un corps de siège du siège éjectable (1) comprend un siège supérieur (12) et un siège inférieur (11), qui sont disposés verticalement. Un mécanisme d'éjection (13) est disposé entre le siège supérieur (12) et le siège inférieur (11). Un rail de guidage (14) est disposé sur l'un parmi le siège supérieur (12) et le siège inférieur (11), un angle du rail de guidage (14) par rapport à l'autre parmi le siège supérieur (12) et le siège inférieur (11) peut être ajusté, et l'autre parmi le siège supérieur (12) et le siège inférieur (11) est en ajustement coulissant avec le rail de guidage (14). Le siège supérieur (12) et le siège inférieur (11) se déplacent l'un par rapport à l'autre dans une direction d'extension du rail de guidage (14) lorsque le mécanisme d'éjection (13) fonctionne. Un capteur environnemental (16) est disposé sur le siège supérieur (12), et le capteur environnemental (16) est utilisé pour détecter si un obstacle est présent dans la direction d'extension du rail de guidage (14). Au moyen du siège éjectable, il est possible d'empêcher qu'un conducteur ou un passager n'entre en collision avec l'obstacle pendant un processus d'éjection, améliorant ainsi la sécurité et la probabilité d'évacuation du conducteur ou du passager sur le siège supérieur.
