Abstract: A headlight horizontal lighting pattern adjustment system includes an inclination angle sensor connected to a vehicle to sense an inclination angle value of the vehicle. A processing unit receives the inclination angle value and processes the inclination angle value into a driving value. A driving module drives a lighting device. The driving module commands the driving device to driving and rotate the lighting device according the driving value. The headlight horizontal lighting pattern adjustment system is equipped to a motorbike or an electric motorbike. When the motorbike turns and tilt, the processing unit adjusts the light of the lighting device by the driving module and the driving device to eliminate dark corners in the dark zone and maintains the full scale of light pattern to enhance safety to all the road users.

Abstract: A lawn chair includes a seat member disposed between left and right leg units, a backrest member extending uprightly from the seat member, and left and right armrest member fastened pivotally to the backrest member at rear portions thereof. Two tension springs are fastened to the armrest members and the leg units for urging the backrest member to a predetermined inclination relative to the seat member. Downward pressure on the backrest member by virtue of body weight of a seated person against tension force of the springs, and a simultaneous upward lifting of the armrest members relative to the leg units result in adjusting the backrest member to a desired inclined position relative to the seat member. Removal of the downward pressure from the backrest member can result in restoration of the backrest member to the predetermined inclination.
