Description
Technical Field
[0001] The invention relates to the field of sofas, and in particular to a cinema sofa. Background Art
[0002] Cinemas are generally equipped with rows of cinema sofas for moviegoers to sit on while watching movies. During the movie watching process, it is inevitable that pedestrians will walk back and forth, and at this time, the moviegoers need to retract their feet to avoid pedestrians. For existing cinema sofas, regardless of whether there is a foot avoidance space under the seat cushion, when the moviegoer retracts his calf with the knee joint axis, his calf will be blocked by the sofa cushion and cannot avoid it; when there is a foot avoidance space under the seat cushion, the moviegoer can tiptoe with the ankle joint as the axis and cooperate with the knee joint to avoid it. However, since the heel is not supported, the moviegoer will feel uncomfortable and the resistance of the seat cushion sponge makes it difficult to avoid it. Summary of the invention
[0003] In order to overcome the defects of the prior art described above, the present invention provides a cinema sofa.
[0004] The technical solution adopted by the present invention to solve the problem is:
[0005] The present invention provides a cinema sofa, comprising a backrest assembly, a base assembly and an armrest, wherein:
[0006] The base assembly includes a base frame, a seat frame arranged above the base frame, and a footrest arranged in front of the base frame, wherein the footrest is arranged in an upwardly inclined direction toward the inside of the base frame, so as to form a foot avoidance space under the seat frame;
[0007] The armrest is arranged on one side or both sides of the base assembly, and a notch is arranged at the front lower end of the armrest so that the front lower end surface of the armrest is flush with the front end surface of the footrest.
[0008] The cinema sofa of the present invention can form a foot avoidance space under the seat frame through the design of the missing corner at the front lower end of the armrest and the upward tilt design of the footrest, so that the viewer can tiptoe with the ankle joint as the axis point and cooperate with the knee joint to swing to achieve effective avoidance. At the same time, when the viewer tiptoes, his heel can be supported on the footrest, so that the line between the heel fulcrum and the toe fulcrum, the ground and the footrest form a triangle, so as to achieve better grounding and relatively comfortable avoidance.
[0009] Further, the backrest assembly includes a backrest plate and a first connecting member spaced apart at the bottom of the backrest plate and used to connect with the seat frame, wherein:
[0010] A support portion connected to the first connecting member extends downward from the bottom of the backrest plate, and the support portion includes an upper support portion corresponding to the waist position of a human body and convex forward in an arc shape, and a lower support portion extending vertically downward;

[0012] Therefore, the support portion is provided with a forward arc-shaped protrusion corresponding to the position of the human waist, thereby providing greater support for the human waist, increasing the comfort of the human body leaning on it, and saving materials at the same time.
[0013] Furthermore, the backrest plate is a first main body with a cavity, and the first main body is made by a blow molding process; the first main body is provided with a plurality of recessed holes for enhancing its bearing capacity.
[0014] Thus, the backrest board is made by blow molding, which reduces the weight of the backrest board while ensuring that the backrest board has sufficient supporting force. In addition, by providing a plurality of concave holes for enhancing the bearing capacity of the backrest board, the backrest board is not easily deformed by external force.
[0015] Furthermore, the seat frame is a rectangular frame and includes two horizontal beams arranged at intervals and two longitudinal beams connecting the two horizontal beams. A second connecting member connected to the first connecting member is provided on the horizontal beam of the seat frame close to the backrest plate.
[0016] Therefore, by arranging a first connecting member at the bottom of the backrest plate and arranging a second connecting member connected to the first connecting member on the seat frame, the seat frame and the backrest plate can be detachably connected, thereby facilitating maintenance and replacement and reducing costs.
[0017] Furthermore, the cross beam, the longitudinal beam, the first connecting member and the second connecting member are all metal parts.
[0018] Therefore, the seat frame made of metal parts has higher supporting strength and longer service life compared with the wooden frame.
[0019] Furthermore, the base frame includes two support legs arranged at an interval, wherein:
[0020] The support leg is in an inverted U shape and includes a supporting portion and supporting portions arranged on both sides of the supporting portion;
[0021] The longitudinal beam is detachably connected to the supporting portion;
[0022] A third connecting member for connecting to the footrest is provided on the supporting portion of the supporting leg.
[0023] Furthermore, the supporting leg and the third connecting member are both metal members.

[0025] Furthermore, the support leg also includes a cross bar respectively connecting the two support parts, and the cross bar is provided with a slot for connecting with the hook on the armrest.
[0026] Furthermore, the armrest is a second main body with a cavity, and the second main body is made by a blow molding process; the footrest is an integrally formed injection molded part.
[0027] Therefore, the armrest made by the blow molding process reduces the weight of the armrest while ensuring that the armrest has sufficient supporting force; the footrest is an integrally formed injection molded part, which reduces weight and reduces costs while ensuring strength.
[0028] Furthermore, it also includes a cup holder arranged on the armrest, the cup holder is provided with an inverted hook; the armrest is provided with a first mounting hole, and the first mounting hole is provided with a convex edge that is engaged with the inverted hook.
[0029] In summary, the cinema sofa of the present invention has the following technical effects:
