Air bags in Aria
• In Total six air bags are available in Aria Pride
• 1. Driver air bag mounted inside horn pad which finally mounted on steering wheel
• 2. Co driver air bag which is mounted on dashboard below the plastic
• 3 & 4. two curtain air bags which are mounted above grab handle behind roof liner on LH & RH
• 5 & 6. side air bags which are mounted inside the driver & co driver seat back rest
How air bag works
• Air bag consists of sodium in solid state ( NaN3). During the impact the switch
ignites the sodium. The thermodicamposition chemical reaction takes place
inside the air bag. Due to heat the sodium explodes & sodium oxides & nitrogen
gas is released. The nitrogen gas explodes the bag & blows the bag.

Aria with 6 Air bags44
Aria is the first Indian car to be armed with - 6 full surround airbags. The Driver and
Passenger Air Bags get self-inflated within milliseconds depending on the severity of the
frontal collision. The Side Air Bag and Curtain Air Bags assure complete protection on all
seats in case of sideways collision or rollover. By forming a safety cushion for all
passengers, these Air Bags reduce the likelihood of injuries in a collision

Here are some other interesting facts about the GPS
satellites (also called NAVSTAR, the official U.S. Department of Defense name for GPS):
• The first GPS satellite was launched in 1978. • A full constellation of 24 satellites was achieved in 1994.
• Each satellite is built to last about 10 years. Replacements are constantly being built and launched into orbit.
• A GPS satellite weighs approximately 2,000 pounds and is about 17 feet across with the solar panels extended.
• Transmitter power is only 50 watts or less.
The GPS satellite systemThe 24 satellites that make up the GPS space segment are orbiting the earth about 12,000 miles above
us. They are constantly moving, making two complete orbits in less than 24 hours These satellites are traveling at speeds of roughly 7,000 miles an hour.
GPS satellites are powered by solar energy. They have backup batteries onboard to keep them running in the event of a solar eclipse, when there's no solar power. Small rocket boosters on each satellite keep them flying in the correct path.

The Aria's glove box does away with the old perception of glove boxes as the hiding places for papers and sundry items. The Glove box in Aria is fitted with a chiller which keeps your beverages & chocolates cool. A light has also been provided in the glove box that is automatically switched on as soon as you open the glove box

ABS With EBD
During panic braking or while braking on slippery surfaces with normal brakes, the vehicle goes into a skid and the steering becomes unresponsive, thus resulting in an accident. The Aria is equipped with an Anti-Lock Braking System along with Electronic Brake Force Distribution. The ABS system prevents the brakes from locking. This ensures that the tires retain traction and steering remains responsive, thus preventing accidents. ABS is effective even on slippery surfaces such as wet roads or ice. The Electronic Brake force distribution distributes the brake force as per the dynamic requirement sensed for each wheel while braking. This increases braking efficiency and shortens the braking distance.

Aria is one of the few crossovers in the world with a body over frame construction. This construction provides the car the rigidity and robustness required for Indian roads and multi terrain operation. Moreover, Aria's chassis frame members are made through a new generation technique called hydro forming which makes the frame lighter, stronger and more rigid.

Advantages of Hydro-forming
• Welding is eliminated (or at least minimized), which makes for better
dimensional control because all of the heat from welding can affect a component's geometry.
• Enhancement in yield strength of material due to cold working.
• Consistent high tensile strength and rigidity and optimized weight.
• Based on some estimates hydro formed steel parts are 10-15% lighter
than comparable stamped steel assemblies.
• Reduced scrap,
• lower tooling costs due to fewer parts,
• more uniform wall thickness,
• Depending on the application, it can save weight, improve fuel economy, minimize waste, and result in stronger, stiffer components that require less
welding. It also provides vast improvement in dimensional accuracy in
certain applications
• In addition, hydro-forming is suitable for both low and high volume production.

47
Process salient requirements
• The process doesn’t allow much flexibility in shape design as conventional
stamping, that can lead to some design compromise e.g. Perimeter variation
along the length can not be more than 10-15%. Hence there can be areas
where we may have to put extra material (higher sections) which may not
require from design point of view.
• Material yield strength enhancement takes place with thinning of material.
• High initial investment
• Cycle times are slower
• Relatively inferior knowledge base for process & tool design.
• Industry experts caution that hydro forming is not right choice for every part.

• Traveling in Aria is definitely reassuring that occupants travels inside
crashworthy vehicle that meets all current crash safety norms in the Indian &
European market.
• Incase of crash, the force of the impact will be dampened by the advanced
hydro-formed frame members & the stiffened body shell with crumple zones
built into it.

Puddle lamp
To make sure you step down safely, every Aria is equipped with a puddle lamp
at the bottom of each door. This lamp illuminates the ground below as you
open the door in the dark, thus preventing you from accidentally stepping into a puddle.

The Aria provides one of the most spacious interiors in its class of vehicles. Even after 3 rows
of seating you still have ample luggage space at the back. The flexible seating further
ensures that you make maximum use of the vast space provided inside. The 2nd row has
a 60:40 split and the seats can be independently flat folded or tumbled. They can also be
slide back and forth to create extra leg space for 3rd row occupants. The 3rd row can also
be flat folded along with the 2nd row to provide a long flat bed. The split fold facility in the
2nd row when used with the folded 3rd row, can be used to store longer items such as
bicycles or kayaks

The Driver's seat in the Aria is specially designed for a comfortable and pleasurable driving
experience. The seat is adjustable 6 ways which includes height adjustment to facilitate an
optimal driving position. The driver's and co driver's seats have arm rests that can
comfortably adjust to any position. And that's not all; the adjustable lumbar support
provides support to the lower back particularly on long journeys. The comfortable seating
position is complemented by a height adjustable seatbelt. This ensures that the driver is
securely fastened to the seat, irrespective of his height.

• To make sure a seatbelt restrains an occupant as early as
possible in a crash, thereby reduce the load on the occupant in a
violent crash, Aria is provided with pretensioners. These tighten
the belt during the very first fractions of a second in a crash.
Pretensioner also reduce the risk of "submarining" (the car
occupant slip under a loosely tightened seatbelt). Aria
pretensioners use pyrotechnic devices that are typically
controlled by the same sensor system as the airbags.
• Pretensioner devices can be added to any of the belt anchorage
points, however, lap pretensioners are normally used in
combination with retractor or buckle pretensioners. All systems
can be tuned to maximize the protection for the occupant.
• These are also called as rotopretensioner load limiter (RPLL)

• On the base version of Aria ELR belts are provided for safety of
occupants without pretensioner & load limiter
