Abstract
A rail vehicle with at least two impact-absorbing posts (RS1, RS2) which are disposed in a front end region (END) and extend vertically to the floor (BOD) of the rail vehicle. A deformable area (KZO) is provided on the front side of the floor (BOD) and each impact-absorbing post (RS1, RS2) is connected to the roof section (DAB) of the rail vehicle via the upper-end region (OE1, OE2) thereof, each impact-absorbing post having, in the respective upper-end region thereof, a pre-determined collapsible region (OE1, OE2) where the buckling (SK1, SK2) of said post should occur in the event of a collision.
Claims5
A railroad vehicle comprising:
- at least two collision posts disposed in an end region of the railroad vehicle and extending perpendicularly to a floor of the railroad vehicle,
- wherein a crumple zone is located at a front end region of the floor and each of the collision posts is connected at its upper end region to a roof region of the railroad vehicle,
- wherein each of the collision posts has a buckling region in its upper end region where each post is adapted to buckle upon collision by having thereat a construction weaker than remaining portions of the post, and
- wherein the collision posts are configured as door posts of a door opening.
