摘要： A safety lock for folding chair includes a top portion and two lateral wall portions to define an open-bottomed receiving space therebetween. The safety lock is mounted to a rear end of a seat frame tube of the folding chair by extending a shaft pin through two shaft holes provided at a rear end of the safety lock and two through holes provided on the seat frame tube, so that the safety lock may be pivotally turned about the shaft pin between a lock position, in which the seat frame tube is clamped in the receiving space and the folding chair is prevented from collapsing, and a release position, in which the safety lock is turned away from the seat frame tube. The two lateral wall portions have two bottom edges that are always located at finger accessible open positions to facilitate easy turning of the safety lock.

摘要： A tensional support arrangement includes a pair of guiding holders rotatably connected to back supporting frame legs respectively and a pair of side supporting arms, which are positioned at two outer sides of a chair frame, each has a support portion pivotally connected to the respective front joint at a front end thereof and a guiding portion slidably connected to the respective guiding holder, wherein two side edge portions of a seat fabric are substantially supported by the support portions of the side supporting arms respectively. Therefore, the tensional support arrangement is capable of substantially increasing the supporting area of the fabric seat to more evenly distribute and support the downward pulling force and stress applied by the user's weight.

摘要： An upholstered foldable furniture system having a first assembled configuration for seating and a second unassembled configuration for storage and shipping. The furniture system has a horizontal seat support frame having front and rear support frame members, spaced left and right side support frame members, a back member having a bottom back member rotatably secured to the rear support frame member and left and right back side support members. The back member is rotatable between a position substantially parallel to the horizontal seat support frame and an angle of not less than 90° with respect to the horizontal seat support frame. Left and right arm members are provided, each having a rear arm frame and a lower arm frame. The left and right lower arm frames are secured to the left and right side support frame members respectively. The furniture system also provides left and right latch assemblies. When the furniture system is in the first assembled configuration for seating, the back member is in a substantially vertical position, the left and right arm members are in substantially vertically upward positions, and the left and right latch assemblies are latched. When the furniture system is in the second unassembled configuration for storage and shipping, the back member is in a substantially horizontal position, and the left and right latch assemblies are unlatched.

摘要： A foldable chair frame includes cross-shaped front and rear leg units, and first and second side frame units. Each of the side frame units includes first, second and third side leg members, and a coupling member. The first side leg member has two ends respectively connected to a lower front leg part of one of the front leg units and an upper rear leg part of one of the rear leg units, and an intermediate leg portion pivotally connected to the coupling member. The second side leg member has two ends respectively connected to an upper front leg part of one of the front leg units and a front end section of the coupling member. The third side leg member has two ends respectively connected to a lower rear leg part of one of the rear leg units and a rear end section of the coupling member. One of the second and third side leg members is connected pivotally to the coupling member to permit movement of the second and third side leg members away from the first side leg member to an unfolded position. The coupling member is provided with first and second limit units to arrest movement of the second and third side leg members relative to the first side leg member when the chair frame is folded.

摘要： A folding massage chair structure, the innovative features of which includes the fixing of guide sleeves at the rear surface of the chair back. The guide sleeves have inserted through them guide rods and the center sections of the guide rods are conjoined to the seat cushion. The lower sections of the guide rods are conjoined to the chair leg. There are support plates installed on the lower guide sleeves, with the upper ends of the support plates conjoined to rear end of the seat frame. When the seat cushion is pulled upward, the pivotably interconnected structure allows the massage chair to be completely folded.

摘要： A folding chair has a rigid support frame with a curved spline profile, and a seat and rear legs which fold into a closed position and substantially collapse within a volume defined by the support frame to maximize stacking density, and to increase stability with the curved spline profiles nesting within one another. The support frame has first and second rigid side support members, each with an upper back support portion and extending forwardly to form front leg portions. The back support portion and the front leg portions are integrally and rigidly connected to advantageously form a curved spline profile. A seat is pivotally coupled to the support frame, or to and between the first and second support members. A majority of the seat advantageously collapses to a folded position within a volume defined between the first and second rigid side support members. Rear legs are pivotally coupled to the support frame, or to the respective first and second support members. A majority of the rear legs advantageously collapses to a folded position within the volume defined by the support frame between the first and second rigid support members.
