“…Observations and measurements are made to determine whether the strength and performance of the WTORS are satisfactory under the test conditions. As in other types of crash tests, forces and accelerations are recorded at selected points and high-speed cameras are used [11,13,14]. It should be stressed that not all wheelchairs are crash tested.…”

Ensuring the free movement of disabled people, including the use of vehicles, is a fundamental right. Therefore, efforts should be made to draw up standards regulating both organisational and technical aspects related to the construction and testing of wheelchairs. The main purpose of the paper is a review the literature related to wheelchair transport safety and the current standards for wheelchair crash testing Wheelchair users must securely and safely attach their wheelchair to the vehicle when travelling. The most common methods include securing with a four-belt system or using docking systems. Docking systems allow the disabled person to restrain the wheelchair themselves. Their main limitation is the lack of standardisation. Issues related to in-vehicle wheelchair design and testing are mainly described in international ISO standards and, in the US, in ANSI standards. Not all wheelchairs are crash tested. Before using wheelchairs, it should be checked if they can be mounted in a car. An important issue is education of wheelchair users and their carers on proper wheelchair securing. Even when wheelchairs are effectively secured, occupants in wheelchairs could be seriously and fatally injured because of improperly used and positioned belt restraints.

“…Such tests (TZ1, TZ2) were carried out at the Łukasiewicz Research Network -Automotive Industry Institute (PIMOT) in Warsaw [10]. The Federal Motor Vehicle Safety Standard (FMVSS) 214 procedure significantly differs from the course of the conventional right-angle crash test [11].…”

“…Hence, a need arises to assess the quality of the data used for the modeling, taken out of necessity from various crash tests. Several stages of such an analysis have been described in publications [10,11]. Analyses of this kind are carried out with using appropriate analytical or simulation models derived from the theory of mechanics [12].…”

The kinematics of the process of deformation of the motorcar body side in the culminating phase of a front-to-side vehicle collision has been examined as a possible basis for analyzing and modeling the process of emergence of a hazard to car occupants during a road accident. The course of such accidents has a complex nature and their models are necessarily based on the approximation of non-linear elastoplastic characteristics of impact processes, especially during the transition from the compression phase to the restitution phase of the deformation process. For such characteristics to be obtained, a lot of experimental tests have to be carried out. This paper addresses the short-duration processes with a high degree of complexity.A front-to-side motorcar collision model has been prepared, which made it possible to analyze the process of deformation of the car body side and the emergence of a hazard and injuries to car occupants. The results of calculation of the deformation rate and range in various car body zones, velocity of the test dummy placed on driver’s seat and velocity of possible dummy’s impact against the car body side being deformed may be taken as a basis for designing effective occupant protection systems. The kinematics of the phase of vehicle contact and deformation process was modeled with taking into account results of experimental tests, including the curves characterizing the largely non-linear processes that are decisive for the deformation of the car body side. The deformation processes analyzed on these grounds showed at the same time the range of penetration of the deformed body part into the car interior, which causes a hazard to vehicle occupants. The calculation results have shown e.g. that the car body side is deformed to a depth of 0.2 m as quickly as within 0.02–0.03 s. At such a car body side deformation range, the car body part being deformed hits occupant’s body in his/her hips and pelvis area with a velocity of about 6 m/s.

“…The course of the front-to-side collision is more complex than the frontal collision [1]. In such a collision, the vehicles move relative to each other not only in the direction of the impact, but also in the transverse direction [2]. Significant hazard in the event of a side impact occur in case of the vehicle body deformation into the passenger compartment and of the dynamics of IOP Publishing doi:10.1088/1757-899X/1247/1/012024 2 the struck vehicle lateral displacement.…”

A vehicles’ collision is a complex energy process, determined by many factors. In the front-to-side collision, the hazards for he occupants of the struck vehicle results from the inertial loads they are subjected to together with the vehicle and from excessive deformation of the bodywork, often involving the space occupied by people. Action is needed to reduce this hazard. One of such actions is to increase the stiffness of the side part of the vehicle body in order to limit the range of its deformation. However, this is an activity that requires a compromise approach, because as stiffness increases, greater lateral forces on the struck vehicle will occur, which will result in inertial loads. The aim of the study is to assess the impact of changes in the stiffness of the side part of the bodywork on the course of the hazard emergence process during a front-to-side vehicles’ collision. Model tests in the PC-Crash program have been prepared and implemented. Their results allowed to establish the relationship between the increased side-stiffness and the characteristic values of physical quantities, which are the measure of the hazard and its effects in a vehicles’ collision.
