The seating mechanism 102 also includes a footrest actuation axle 120 extending generally laterally between the first and second sides 108 and 110 and rotatable about an axis of rotation extending generally laterally between the first and second sides 108 and 110. The seating mechanism 102 also includes a rear member 121. The footrest actuation axle 120 and the rear member 121 may be longitudinally spaced generally parallel and laterally oriented front and back members of a frame. Further, the seat support bodies 110 and 112, the footrest actuation axle 120, and the rear member 121 may be members of a generally quadrilateral frame.
On the first side 108, the footrest actuation axle 120 is coupled to a footrest actuation cam 122 extending eccentrically to the axis of rotation of the footrest actuation axle 120. Also on the first side 108, the seating mechanism 102 includes an actuator 124 operable to exert a force on the footrest actuation cam 122 to rotate the footrest actuation axle 122 about its axis of rotation. On the second side 110, the footrest actuation axle 120 is coupled to a footrest actuation cam 126 extending eccentrically to the axis of rotation of the footrest actuation axle 120. Also on the second side 110, the seating mechanism 102 includes an actuator 128 operable to exert a force on the footrest actuation cam 124 to rotate the footrest actuation axle 122 about its axis of rotation. Therefore, individually or collectively, the actuators 124 and 128 may exert torque on the footrest actuation axle 120 to rotate the footrest actuation axle 120 about its axis of rotation.
In the embodiment shown, the actuator 124 includes an electric motor operable to rotate a threaded shaft, and rotation of the threaded shaft causes linear extension or contraction of the actuator 124 to exert a torque on the footrest actuation axle 120 to rotate the footrest actuation axle 120 about its axis of rotation. Also, in the embodiment shown, the actuator 126 is substantially the same as the actuator 124, and the motors of the actuators 124 and 126 may be synchronized motors. However, alternative embodiments may differ. For example, actuators of alternative embodiments may include pneumatic or hydraulic actuators, or other actuators, and actuators of alternative embodiments may not necessarily be linear actuators.
The seating mechanism 102 includes a footrest support body 130 on the first side 108 and a footrest support body 132 on the second side 110. The footrest support bodies 130 and 132 are movable relative to other parts of the seating mechanism 102 (such as the seat support surfaces 114 and 118) in response to rotation of the footrest actuation axle 120 about its axis of rotation in response to actuation by one or both of the actuators 124 and 128. In the embodiment shown, extension of the actuators 124 and 126 causes the footrest support bodies 130 and 132 to rise relative to other parts of the seating mechanism 102 (such as the seat support surfaces 114 and 118), thereby causing a footrest attached to the footrest support bodies 130 and 132 to rise relative to such other parts of the seating mechanism 102, and contraction of the actuators 124 and 128 causes the footrest support bodies 130 and 132 to lower relative to such other parts of the seating mechanism 102, thereby lowering (relative to such other parts of the seating mechanism 102) a footrest attached to the footrest support bodies 130 and 132.
However, alternative embodiments may differ, and may include one or more different actuators that may cause movement of one or more footrest support bodies in other ways relative to seat support surfaces or relative to other parts of a seating mechanism. Further, alternative embodiments may include one or more different actuators that may cause movement of one or more different parts of a seating mechanism or of a seating system relative to other parts of seating mechanism or of the seating system, for example.
The actuators 124 and 128 are on opposite lateral sides of a cavity defined by the seating mechanism 102 and shown generally at 134. The cavity 134 is open on at least one side (a top side in the embodiment shown) or at a same side of the seating mechanism 102 as the seat support surfaces 114 and 118. The cavity 134 has a generally quadrilateral shape in the embodiment shown, although alternative embodiments may differ.
The seating mechanism 102 also includes a recliner interface 136 on the first side 108 and a recliner interface 138 on the second side 110. The recliner interfaces 136 and 138 may cooperate with other structures of the seating system 100 so that the seating mechanism 102 may be supported relative to a surface (such as a floor or ground surface for example), and the seating mechanism 102 may recline or otherwise be movable relative to such a surface. However, alternative embodiments may differ, and for example, seating mechanisms of alternative embodiments may be supported relative to, or movable relative to, other structures or surfaces in other ways.
The seating mechanism 102 also includes a backrest support body 140 on the first side 108, and a backrest support body 142 on the second side 110. The backrest support bodies 140 and 142 may support a backrest relative to the seating mechanism 102 on a same (for example, top) side of the seating mechanism 102 as the support surfaces 114 and 118.
Some or all components of the seating mechanism 102, such as frame members described above for example, may be metallic. Further, the seating mechanism 102 may incorporate some parts from one or more seating mechanisms that are disclosed in PCT publication no. WO 2018/211395 A1.

In the embodiment shown, the base 145, the mounting flange 146, the sidewall 147, the opening 148, the receptacle 150, the cavity 152, and the support surface 154 are all generally quadrilateral, although alternative embodiments may differ. Further, in the embodiment shown, the support body 144 may be made of a thermoplastic material, but again alternative embodiments may differ.

The seat cushion support assembly 104 also includes inserts (from foam, for example) 158, 160, 162, and 164, which may be positioned between the spring assembly 156 and the sidewall 147 around the cavity 152 to maintain a position of the pocket coil assembly 156 in the cavity 152. The seat cushion support assembly 104 also includes a three-dimensional adaptation fabric (or, more generally, a flexible cover) 166, which may be supported (on top, for example) on the pocket coil assembly 156 when the pocket coil assembly 156 and the inserts 158, 160, 162, and 164 are positioned in the cavity 152 so that the three-dimensional adaptation fabric 166 may be supported for resilient deformation on the pocket coil assembly 156 and on the seat cushion support body 144. The three-dimensional adaptation fabric 166 may be positionable to extend over the mounting flange 146 and cover the spring assembly 156.
The seat cushion support assembly 104 may incorporate some or all parts from one or more modules that are disclosed in PCT publication no. WO 2018/114062 A1.

The second support surface 172 is sized to be positioned against the seat support surfaces 114 and 118, and the support surface 154 is sized to be positioned against the first support surface 170. The through-opening 174 and the cavity 134 are also sized to receive at least a portion of the receptacle 150. When the support surface 154 is positioned against the first support surface 170, and when the second support surface 172 is positioned against the seat support surfaces 114 and 118, at least a portion of the receptacle 150 is received through the through-opening 174 and into the cavity 134, and at least a portion of the receptacle 150 is positioned in the cavity 134 laterally relative to one or both of the actuators 124 and 128 or laterally between the actuators 124 and 128. Therefore, when the support surface 154 is positioned against the first support surface 170, and when the second support surface 172 is positioned against the seat support surfaces 114 and 118, the seat support surfaces 114 and 118 may support the seat cushion support body 144 indirectly. Nevertheless, reference herein to support may include direct support or indirect support (such as indirect support involving an interface support body such as the interface support body 168, for example).

Seating systems such as the seating system 100 may be included in other seating systems. For example,
With reference to
The module 1104 may have a carrying container/cushion support body/carrier tray 1144 formed in trough-shape. Support body 1144 may have a bottom/base 1455, in which ventilation holes can be provided. From the bottom 1455 side walls 1445 extend upwards. The upwardly extending side walls 1445 have an outwardly bent peripheral upper edge 1146, so that the assembled module can be suspended from above into an opening of a sitting or lying furniture surrounded by a support frame.
The carrying container 1144 shown in
In the assembled state of the module 1104, a protective layer 1149 may be applied to the top of the bottom/base 1445. This protective layer 1149 is preferably a protective mat. As a protective mat, for example, a non-woven mat may be used.
Furthermore, in the assembled state of the module 1104, a resilient component 1143 is placed on the protective layer 1149, in which case it is a Bonnell or Belleville spring core. The fleece mat provided as a protective mat underneath the Bonnell or Belleville spring core serves in particular for noise reduction.
Between the side walls 1445 of the carrying container 1144 and provided in the interior of the carrying container 1144, one or more intermediate members 1147 may be inserted, such as for example a total of four foam beams 1147, each of which is provided on a different outer side of the carrying container 1144.
The side walls 1445 of the carrying container 1144 extend from the bottom 1455 either vertically upwards or obliquely upwards. In the case of side walls extending vertically upwards, the foam beams 1147 are cuboid-shaped. In obliquely upwardly extending side walls, the foam bars are formed wedge-shaped so that they are adapted to the slopes of the side walls. In this case, the foam bars serve as slope compensation. In both aforementioned cases, the foam bars serve as protective components for the Bonnell or Belleville spring core 1143 located in the carrying container 1144.
Furthermore, the module 1104 in its assembled state, has on top of the resilient member/component 1143 a cover 1148. This cover is, for example, a cover mat that may be made of a 3D fabric. This 3D fabric may be elastic and air permeable. As an alternative to a 3D fabric, the cover 1148 may also be formed by a pressure distribution fabric. This causes in the assembled state of the module, a distribution of pressure exerted by a person sitting on the module pressure on adjacent springs of the spring core. Preferably, the length and the width of the cover 1148 are chosen to be greater than the length and the width of the resilient component 1143, that the cover 1148 protrudes laterally on all four sides of component 1143 and also on the intermediate members 1147.
In its areas laterally beyond the intermediate members 1147 protruding areas, the cover 1148 is fixed on the top of the peripheral edge 1146 of the carrying case 1144. This attachment is preferably realized by a UV welding or by a bond, which can be carried out for example by means of a two-sided adhesive tape.
The module 2104 includes four foam beams 2147, each of which is provided on a different outer side of the pocket spring core 2143.
In both aforementioned cases, the foam bars 2147 serve as protective components for the pocket spring core 2143 located in the carrying container 2144.
Cover is 2148 is, for example, a cover mat made of a 3D fabric. This 3D fabric may also be elastic and breathable. As an alternative to a 3D fabric, the cover 2148 may also be formed by a pressure distribution fabric. This causes in the assembled state of the module, a distribution of pressure exerted by a person sitting on the module pressure on adjacent springs of the spring core 2143. Preferably, the length and the width of the cover 2148 are chosen to be greater than the length and the width of the pocket spring core 2143, that the cover 2148 on all four sides protrudes laterally beyond the pocket spring core 2143 and also via the intermediate members 2147.
In its laterally beyond the intermediate members 2147 protruding areas, the cover 2148 is fixed on the top of the peripheral edge 2146 of the carrying case 2144. This attachment is preferably realized by a UV welding or by a bond, which can be carried out for example by means of a two-sided adhesive tape.
In the assembled state of the module 3104, a resilient component 3143 is placed on the bottom 3445 of the carrying container 3144, and component 3143 is a gel cushion component. As an alternative to a gel cushion component, the resilient component 3143 may also be a foam component or a component having a liquid-filled cushion.
No intermediate components are necessary between the side walls 3455 of the carrying container 3144 and the gel cushion component 3143 provided in the interior of the carrying container, since the outer shape of the gel cushion component adapts to the course/configuration of the side walls 3455 even when the side walls are inclined.
Furthermore, the module 3104 in its assembled state has on the top of the gel pad component 3143, a cover 3148 like the covers described above. In the assembled state of the module 3104, this causes a lateral distribution of the pressure exerted by a person sitting on the module. Preferably, the length and the width of the cover 3148 are selected to be greater than the length and the width of the gel cushion component 3143 such that the cover protrudes laterally over the gel cushion component 3143 on all four sides.
In its laterally areas beyond the gel component 3143, the cover 3148 is mounted on the upper side of the peripheral edge 3146 of the carrying container 3144. This attachment is preferably realized by a UV welding or by a bond, which can be carried out for example by means of a two-sided adhesive tape.
