Description:CRASH PROTECTION SYSTEM FOR BUSES

FIELD OF THE DISCLOSURE
[0001] This invention generally relates to a field of vehicle protection systems and in particular, to a crash protection system for buses that efficiently absorbs impact energy and reduces forces transmitted to the buses.
BACKGROUND
[0002] The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed technology.
[0003] In the context of vehicle safety, frontal collisions remain one of the most hazardous types of accidents, often resulting in catastrophic damage to the vehicle and severe injuries or fat , C , Claims:We Claim:
1. A crash protection system (102) for buses, comprising:
a crumple zone assembly (104) configured to be mounted at a front portion (112) of a bus (100), wherein the crumple zone assembly (104) having:
a top portion (106) comprising:
a transverse beam (116) configured to be coupled with an A-pillar (114) of the bus (100),
a first cross member (118) attached to the transverse beam (116), and
a first set of crash boxes (128) positioned between the first cross member (118) and a cowl (126) of the bus (100),
a middle portion (108) comprising:
a second cross member (120) connected to the first cross member (118),
a chassis plate (130) secured to a chassis (200) of the bus (100), and
a second set of crash boxes (132) positioned between the second cross member (120) and the chassis plate (130),
a bottom portion (110) comprising:
a front underrun protection assembly (122) attached to the chassis (200) and the A-pillar (114) of the bus (100),
a third set of crash boxes (300) integrated into the front underr
