JASTI CO., LTD. You can make it with JASTI. JASTI will cooperate with your every demand for the human safety.



All these dummies are manufactured and certified in Japan to be specified under CFR 49, Parts 572. These dummies are used for a kind of car crash tests, frontal impact and frontal offset impact. Used as weight dummy for sled test, we supply some special parts to prevent from easy breakages (see R&D dummy parts). For pedestrian dummy, it is used for R&D purposes, such like evaluation for pedestrian/cyclist/rider injury. We receive any offers to modify the dummy parts, to assemble the sensors on requested parts and/or to have the original specifications and performances.

For Front Impact Test Dummy

Hybrid-III50th Percentile Male Dummy / Hybrid-III5th Percentile Female Dummy

Hybrid-III50th Percentile Male Dummy /Hybrid-III5th dummy Female for the front collision tests.
JASTI manufactures Hybrid-50th and 5th dummy in according to US Standard of NHTSA (National Highway Traffic Administration) and [49CFR Part572 Subpart E and O]. To prove the performance of dummies, JASTI carry out in-house calibration tests with traceability proving the certification of conformity with the regulation. All parts are manufactured as per said drawing and regulation and it is compatible JASTI parts with other dummies. Hybrid-III50th Percentile Male Dummy /Hybrid-III5th dummy Female are being used not only for front impact test, but also it is broadly used with the examination for the injury assessment.

Hybrid 95th Percentile Large Male

The first Hybrid III 95th prototype was completed in 1989 defining the specification for adult size small female and adult size large male dummies having at least the same level of biofidelity and measurement capacity as the Hybrid III 50th percentile dummy.
Scaling techniques were used to define the new dummy designs and biofidelic responces.
Mass and geometric scaling factors were calculated for various body segments. The scale factors were applied to the HIII 50th detail drawings thus insuring each dummy has similar design concept as the 50th as well as corresponding body segments’ densities.
1The scaling technique were also applies to the biomechanical impact response of the HIII 50th head, neck, chest and knee to give corresponding biomechanical responses.
The pelvis design was not directly scaled from the HIII 50th but rather a new concept.
In 1997, in response to serious injuries and fatalities attributed to airbag development, SAE, NHTSA began a major project to optimize the HIII family dummy design and improved the measuring capability and biofidelity of the crash dummies to better evaluate neck and chest potential injury.
HIII 95th large male is used primarily to test seat belts integrity or as a ballast dummy as of today.

Hybrid-III50th Percentile Male Dummy is specified under CFR 49, Parts 572, Subpart E. Of course our H-III50th Dummy is manufactured to meet above regulation including certification test. We checked the compatibility between our dummy and other manufacturer’s. You can be satisfied with our dummy/dummy parts which have high quality and constant quality level

Pedestrian Dummy

Pedestrian Dummy

Left) Hybrid III 5th Percentile Female Pedestrian Dummy
Cener) Hybrid III 50th Percentile Male Pedestrian Dummy
Right) Hybrid III 95th Percentile Large Male Pedestrian Dummy
Pedestrian Dummy is modified dummy from Hybrid III 50M,5F and 95LM based, which is used for frontal collision test, keeping its original weight specification and basic function, but minimum parts of pelvis, lumbar spine and knee slider are replaced for standing posture one. Pedestrian dummy can be set up and replicate biological behavior likely human-being, it is useful to measure injury value in other tests besides automotive collision purpose. Pedestrian dummy is used for not only pedestrian protection field, but also more widely fields such as motorcycle rider’s protection, robot safety assessment,falling accident at construction field, buried accident caused of environmental disaster, etc. Meanwhile,it can be also used as a weight dummy in the body handling, rescue/nursing training, durability test of commodity and so on. 3 types of different pedestrian dummies are available from JASTI, 50M adult dummy, 5F woman and 95LM large male dummy,.Each type can be replicated for any conditions of where human is exposed in the risk of injury or the death. Pedestrian Kit Parts are also available and it is easily reassemble from Hybrid III to Pedestrian dummy with minimum cost. Please feel free to contact to JASTI if you have any needs of Pedestrian Dummy.

FAA Dummy

FAA Dummy was developed for the US Federal Aviation Administration to evaluate the airplane seat of aircraft accident based on Hybrid-Ⅲ50th Percentile Male Dummy. The difference with Hybrid-Ⅲ50th Percentile Male Dummy are the gross weight and sitting height of Lower Torso, Abdominal Insert, Femur and Upper Leg Bone, that

Gross Weight:164 LBS(74.4kgs) Sitting Height:37.5inches(90.7cm)

FAA Dummy is specified in the Standard of
CFR 14 Parts 23.562, 25562, 27.562, 29.562.

For Side Impact Test Dummy

ES-2re Side Impact Dummy
