Abstract
Una silla comprende una sola pieza de asiento y soporte para la espalda, doblada de modo de formar un soporte de asiento inferior sustancialmente en forma de U, y un soporte para la espalda superior, sustancialmente erecto. El soporte de asiento incluye porciones inferior y superior de pata y una porción de vuelta entre las mismas. La porción de vuelta es elástica, con ello permitiendo a la porción superior de pata desviarse hacia abajo con relación a la porción inferior de pata, y al soporte de espalda moverse hacia abajo y atrás en respuesta a una fuerza descendente ejercida sobre la porción superior de pata. Además la silla comprende medios estabilizadores montados entre las porciones superior e inferior de pata del soporte de asiento para proporcionar estabilidad a la misma durante la deflexión descendente relativa de la porción superior de pata. La silla comprende además medios elásticos de atiesamiento y medios de control de tensión. Los medios de atiesamiento están montados en y entre las porciones superior e inferior de pata del soporte de asiento y funcionan para incrementar la resistencia con relación a la deflexión de la porción superior de pata. Los medios de control de tensión están montados moviblemente con relación a la porción inferior de pata del soporte de asiento para vinculación ajustable con los medios de atiesamiento para ajustar la resistencia de éstos a la deflexión relativa de la porción superior de pata del soporte de asiento.A chair comprises a single seat and back support piece, folded so as to form a substantially U-shaped lower seat support, and a substantially erect upper back support. The seat support includes lower and upper leg portions and a lap portion therebetween. The back portion is elastic, thereby allowing the upper leg portion to deviate downward relative to the lower leg portion, and the back support to move down and back in response to a downward force exerted on the upper leg portion. paw. In addition the chair comprises stabilizing means mounted between the upper and lower leg portions of the seat support to provide stability thereto during relative downward deflection of the upper leg portion. The chair further comprises elastic stiffening means and tension control means. The stiffening means is mounted in and between the upper and lower leg portions of the seat support and functions to increase the resistance relative to deflection of the upper leg portion. The tension control means are movably mounted relative to the lower leg portion of the seat support for adjustable engagement with the stiffening means to adjust the resistance of the latter to relative deflection of the upper leg portion of the seat support.
