automobile model and desired styling of the upholstery.
• The yarn required for the seat covers is in the range of
500 deniers to 1300 deniers.
• The fabric is further laminated to provide desired
protection characteristics.

11. HELMET

12. HELMET
• The principal function of a helmet is to absorb the shock
of a crash and thus put a stop to major injury to the
brain, rather than preventing head and face crack.
• The usual motorcycle helmet has an internal layer of
polystyrene or polypropylene foam and an external
layer made of plastic, glass, and other man-made fibres.
• The outer shell is made from Acrylonitrile-Butadiene-
Styrene (ABS) or Polypropylene or glass fibre plastic
which is hard in nature.
• The inner side of the shell is expected to provide cushion
to the rider and is made from regulated density
concussion padding.

13. Sunvisors

14. Sunvisors
• The sun visors are located in the interiors of a
four-wheeler just above the windshield.

parts,
– The synthetic backbone made of polypropylene
or kenaf fibres.
– Scrim = coarse woven reinforcement fabric and
– Upholstery = typically artificial leather.

16. Seat Belt

17. Seat Belt
• Seat belts function as a safety harnesses
which secure the passengers in a vehicle
against harmful movements during collision
or similar incidents.
• Seat belts are woven narrow fabric made
from nylon filament yarns or high tensile
polyester filament yarn.
• The load specification is an important
criterion for usage in vehicles.

18. Seat Belt
Product Characteristics:
• Are made from nylon filament yarn or polyester filament yarn
which is woven to produce the webbing pattern.
• The linear density of man-made yarns must be stuck between
100dtex and 3000dtex, preferably 550-1800dtex.
• A typical seat belt is made of 320 ends of 1,100 dtex polyester
each.
• The majority weft yarns prepared from polyester are 550dtex.
• The critical characteristics of the webbing are:
– Abrasion resistance,
– Resistance to light and heat,
– Capable of being removed and put back in place easily and good
retraction behavior.
– The load bearing capacity of seat belts is 1500 kilograms.

19. Interior carpets

20. Interior carpets
• The carpets are laid in the cabin and parcel
shelf at the back.
• The carpets are primarily non-woven textile
material.
• The usage of carpets varies based on the
interior designs which vary across car
models.
• Usage of carpets in buses and other
M&HCVs is minimal.
