Safety Aspects of the Benz Patent Motor Car from 1886

• Comfortable and safe

• Easier and safer to operate

compared to horse buggies


Mercedes-Benz – The Cradle of Vehicle Safety


More than 75 Years of Experience in Passenger-Car Safety Development

1939 The „Father of Passive Safety“, Béla Barényi, was employed by Daimler-Benz.

1959 Crumple Zone, Rigid Passenger Cell and Interior Paddings were implemented in series production for

the first time.

Preventive pre-conditioning of the occupants

• Idea: reduce the effects of noise stress caused by

collisions

• Function: If the car detects certain critical situations, the

sound system emits a short pink noise signal

Reflex mechanism

• Pink noise pattern is able to make the stapedius muscle

contract

• Protective effect: reduced noise effect on the inner ear




Phase 1:

Safe driving

Phase 2:


Phase 3:

During a crash

Phase 4:

After a crash


Restraint Systems (Example: S-Class)


Driver airbag

Kneebagfor the driver

PRE-SAFE® belt tensioner and adaptive belt force limiter for driver and front passenger

Pyrotechnical belt pretensionerand self-adaptive belt force limiter at the outside seats in the rear compartment

Sidebags for front and rear

WindowbagsCurtain-airbags for front and rear seats

Front passenger airbag with active vent

Beltbag - inflatable seatbelts for outer rear-seat passengers

PRE-SAFE® rear seat-belt buckles for outer rear-seat passengers

PRE-SAFE ® Impulse pretensioner and load limiter for driver and front passenger

Seat cushion airbag (executive reclining seat)

Highly

sophisticated

restraint systems

Advanced restraint

systems in combination

with an intelligent body

design are the key for

efficient occupant

protection.

The Key Principles of Passive Safety


1) Dissipate energy during a crash

2) Maintain a stable passenger compartment

3) Provide proper restraint of the occupant

red: crash-relevant structures, mainly made of high strength steel

purple: ultra high-strength steel

blue: aluminium parts




Phase 1:

Safe driving

Phase 2:


Phase 3:

During a crash

Phase 4:

After a crash


After a Crash – depending on the severity of the crash


- Activate for instance: hazard warning lights, interior lights,

door position lights

- Automatic Collision Notification (Emergency Call)

- Lower front windows to ventilate the interior

- Warn other vehicles by car-to-car communication

- Automatic engine off switch
