‐ at least a deformable element (104) provided on at least a surface of the
5 collapsible frame (100), characterized in that the collapsible frame
(100) collapses along at least a preferential axis based on location of at
least the deformable element (104).
2. The collapsible frame (100) as claimed in claim 1, wherein said at least a
10 deformable element (104) is selected from the group consisting of a bead, a
notch, a recess, a dimple, and combinations thereof.
3. The collapsible frame (100) as claimed in claim 1, comprising at least a first
collapsible zone with at least a first deformable element (104-1); and at least
15 a second collapsible zone with at least a second deformable element (104-
2).
4. The collapsible frame (100) as claimed in claim 1, comprising a first Cbeam (106-1) and a second C-beam (106-2), wherein the first C-beam (106-
20 1) and the second C-beam (106-2) are fixedly coupled in opposing
orientation to each other.
5. The collapsible frame (100) as claimed in claim 1, wherein the collapsible
frame (100) has a first end (108) and a second end (110) defined along the
25 longitudinal axis (112) of the collapsible frame (100), and cross-section of
the first end (108) is different from the cross-section of the second end (110).
6. A chassis assembly (200) of a vehicle (300) comprising at least a collapsible
frame (100) as claimed in claim 1, wherein at least the collapsible frame (100) is fixedly attached to at least a first end of a first member (202) of the
chassis assembly (200).
7. The chassis assembly (200) as claimed in claim 6, comprising a first
5 collapsible frame (100-1) and a second collapsible frame (100-2), wherein
the first collapsible frame (100-1) is fixedly attached to a first end of a first
member (202) of the chassis assembly (200) and the second collapsible
frame (100-2) is fixedly attached to a first end of a second member (204) of
the chassis assembly (200).

8. The chassis assembly (200) as claimed in claim 6, comprising at least a first
cross-member (206) adapted to couple the first collapsible frame (100-1)
and the second collapsible frame (100-2) and at least a second cross-member
(208) adapted to couple the first collapsible frame (100-1) and the second
15 collapsible frame (100-2).
9. The chassis assembly (200) as claimed in claim 8, wherein at least the first
cross-member (206) comprises at least a deformable element (210) on at
least a surface of the at least the first cross-member (206).

10. The chassis assembly (200) as claimed in claim 8, further comprising:
‐ at least a first cabin mount (212) fixedly coupled to at least a section of
the first collapsible frame (100-1); and
‐ at least a second cabin mount (214) fixedly coupled to at least a section
25 of the second collapsible frame (100-2),
wherein the cabin mounts (212, 214) are adapted to at least partially
support a cabin (302) of the vehicle (300).
