Sentence examples for backrest during from inspiring English sources

The peak transmissibilities between the accelerations at the seat base and the compressive forces at L5/S1 were highest for the seat without the backrest during the bending posture.

The sitting was individually adjusted to minimise displacement between the lower back and backrest during muscular force exertion and, therefore, to avoid posture change.

A finite element model was developed, a prototype was built and a focus group was made to evaluate the new design function introduced in the previous study: "Dynamic commutation of the backrest angle during the car driving task" in terms of safety and discomfort reduction.

The objectives of this study were to investigate whether fore-and-aft acceleration in the plane of the seat was an adequate predictor of vibration discomfort arising from low frequency oscillation in both the pitch and fore-and-aft axes, and to determine the effect of a backrest on discomfort during pitch and fore-and-aft oscillation at low frequencies.

There are several reasons why the spontaneous (PSV) ventilator mode may be less deleterious on MAP during backrest elevation.

The inclination with respect to gravity of the IMU located on the wheelchair backrest was computed during the stationary phase (which lasted about five seconds) at the beginning of each trial using IMU data and following the pitch-roll-yaw rotation sequence [ 29].

The range of shear displacements along the backrest plane (BS) was significantly larger during sit-to-stand transition (P < 0.01).

The measurements of absorbed power are consistent with backrests being beneficial during exposure to low frequency fore-and-aft vibration but detrimental with high frequency fore-and-aft vibration.

The results of the exploratory study show a decrease in the amount of the discomfort level, and the number of macro reposition movement during the swing movement of the backrest angle compared to the ordinary case (static posture).

The variations in warp yarn tension during the weaving process become smaller by the backrest roller's swinging motion.

(b) The participants typically fixated on two parts of the chairs during their Kansei evaluations, namely the seat and the backrest, indicating that seats and backrests are the two primary features people consider when evaluating chairs.
