pääomansuojapuskuri

Pääomansuojapuskuri refers to a safety feature designed to protect the head during collisions or impacts. Its primary function is to absorb and dissipate kinetic energy, thereby reducing the force transmitted to the occupant's head. This protective mechanism is commonly found in vehicles, particularly in headrests, and also in various forms of protective headgear such as helmets used in sports and industrial settings.

In automotive applications, the headrest's design and material properties are engineered to act as a pääomansuojapuskuri. When a vehicle is struck from behind, the occupant's torso is propelled forward, while their head tends to lag due to inertia. This relative motion can cause whiplash injuries. The pääomansuojapuskuri, integrated into the headrest, is designed to move with the occupant's head and support it, mitigating excessive backward or forward movement and reducing the risk of neck and head trauma.

Beyond vehicles, the concept of a pääomansuojapuskuri is fundamental to the design of helmets. These helmets, whether for cycling, motorcycling, construction, or other activities, incorporate layers of energy-absorbing materials. Upon impact, these materials deform or crush, absorbing a significant portion of the impact energy before it reaches the wearer's skull. The effectiveness of a pääomansuojapuskuri is determined by its ability to manage impact forces across a range of speeds and collision types. Modern safety standards often mandate specific performance criteria for these protective elements.
