At the corner between the vehicle outer side surface and the rear surface of the seat back, it is formed in a concave shape that accepts the angular step shape of the vehicle compartment side wall when locked by the push-in, and by having such a concave shape, The seat back has a configuration in which a substantial width shape that can function as a backrest surface is widely secured.

JP 2011-110962 A

  However, by having the concave shape as described above, the seat back is stretched in an intricate shape along the concave shape so that the angular step shape of the vehicle compartment side wall can be received in the concave shape. It is necessary to make the configuration complicated. The present invention was devised as a solution to the above problem, and the problem to be solved by the present invention is that even if the other member is pushed into the seat pad having a concave shape into which the other member is pushed. An object of the present invention is to make it possible to easily stretch the seat cover so as not to cause a problem.

In order to solve the above problems, the vehicle seat of the present invention takes the following means.
1st invention is a vehicle seat provided with the seat pad which has a recessed part into which another member may be pushed in, and the seat cover coat | covered on the surface of a seat pad. The cover portion covered with the recess of the seat cover has a shape longer than the linear distance between the opening edge portions of the recess and has a slack that is covered in a state of floating from the inner peripheral surface of the recess. Yes. When the other member is pushed into the concave portion, the cover portion is slackened in such a manner that the cover portion is pushed onto the inner peripheral surface of the concave portion to accept the pushing of the other member.

  According to the first aspect of the present invention, since the slack as described above is set in the cover portion of the seat cover, the cover portion is recessed at the position where the cover portion is lifted from the recess at all times before the other member is pushed into the recess. Is covered with the slack and gentle surface shape. Therefore, with a simple configuration in which slack is set in the cover portion, it is possible to obtain a state in which the portion where the recess is formed is covered with the cover portion in a normal manner. When the other member is pushed into the concave portion, the cover portion is slackened in a manner of being pushed onto the inner peripheral surface of the concave portion and receives the pushing of the other member. In this way, the seat cover can be simply stretched so as not to cause a problem even if another member is pushed into the above-described recessed seat pad by a simple configuration that sets the slack in the cover portion. Can do.

  The second invention is the following configuration in the first invention described above. The cover portion is provided in a slack state in a spherically curved shape so as to be recessed in the recess.

  According to the second aspect of the invention, the cover portion is provided so as to be bent in a spherical shape so as to be recessed in a spherical shape. it can.

  The third invention is the following configuration in the first or second invention described above. The cover portion is formed by connecting a plurality of pieces of flexible surface-like pieces, and is set so that a seam allowance between these pieces protrudes to the back side facing the recess.

  According to the third aspect of the present invention, the seam allowance between the pieces of the cover portion is set on the back side facing the recess, so that the cover portion is likely to receive an urging force in a direction in which the cover portion enters the recess. Therefore, with such a simple configuration, the cover portion can be normally held in a state in which the cover portion is disposed in a good-looking state loosened in the recess.

  The fourth invention is the following structure in the third invention described above. The concave portion is formed in a concave shape having an L-shaped cross section and opened in two directions. The cover part is configured by connecting a first piece that covers one surface of the L-shaped concave portion and a second piece that covers the other surface. The first piece has a surface shape that matches one of the L-shaped surfaces of the recess and is configured to be more rigid than the second piece. The second piece is configured to be more extensible than one piece.

  According to the fourth aspect of the present invention, since the rigidity of one piece (first piece) is high, the urging force in the inward direction of the concave portion due to the sewing margin set on the back side of both pieces can be easily increased, and the covering It becomes easy to be held in a state where the portion is slackened in the recess. Also, because the other piece (second piece) is highly extensible, when the other member is pushed into the recess, the rigid first piece is applied to one side of the L-shape of the recess. On the other hand, the second piece having high extensibility can be applied across one side and the other side of the L-shape of the recess, or can be applied to the other side of the L-shape of the recess. Can be easily bent. Therefore, the cover portion can be easily bent along the shape of the recess.

  The fifth invention is the following structure in the fourth invention described above. On one surface of the L-shape of the recess, a lock pin that penetrates and protrudes through the first piece is provided. The other member that may be pushed into the recess is a vehicle wall member provided with a lock mechanism that is pushed into the lock pin and locked.

  According to the fifth aspect of the present invention, even when the vehicle wall member is pushed into the recess when the lock pin is pushed into the lock mechanism provided in the vehicle wall member and locked, the cover portion of the seat cover Due to the slack, no large tension is applied, and no excessive load is applied between the lock pin and the first piece passing therethrough. Therefore, the lock pin can be smoothly locked to the lock mechanism provided on the vehicle wall member without applying an excessive load on the cover of the seat cover.

1 is a perspective view showing a schematic configuration of a vehicle seat of Example 1. FIG. It is the II-II sectional view taken on the line of FIG. It is the perspective view which looked at the seat back from back of the vehicle outside. It is a principal part enlarged view of FIG. It is the VV sectional view taken on the line of FIG.

  EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated using drawing.

  First, the configuration of the sheet 1 according to the first embodiment will be described with reference to FIGS. As shown in FIG. 1, the seat 1 according to the present embodiment is configured as a narrow-side seat that is divided into 6: 4 on the left and right sides in the rear seat of the automobile, and a seat back 2 that serves as a backrest for a seated occupant. And the seat cushion (illustration omitted) used as a seating part and the headrest 3 used as a headrest part are comprised. The seat back 2 is connected in such a manner that the lower end portions thereof on both the left and right sides thereof can be rotated back and forth around the same axis relative to a hinge bracket (not shown) installed on the floor panel. . As a result, the seat back 2 has fallen about the above-described outer rotation shafts so that the seated occupant can use it as a backrest and is folded into the upper surface of the seat cushion. It is in a state provided so as to be rotated up and down between the posture position.

  As shown in FIGS. 2 to 5, the seat back 2 is provided with a lock pin 2 Fc that protrudes in a rod shape on the side of the shoulder opening outside the vehicle, and a lock mechanism 12 that is provided on the step portion 11 of the vehicle interior side wall 10. By being pushed in from the front side and locked, it is fixed to the above-mentioned standing posture position. Here, the above-described seat back 2 has a stepped shape at the corner between the vehicle outer side surface and the rear surface at the front side of the vehicle compartment side wall 10 provided with the lock mechanism 12 when locked by the push-in. A recess 2Pb that can receive the portion 11 is formed. By having such a recess 2Pb, the seat back 2 is formed in a wide shape in which the width of the backrest surface on the front side can be extended to a position on the front side of the stepped portion 11. Has been.

  However, since the seat back 2 has the shape having the recess 2Pb as described above, the cover portion 2Cd of the back cover 2C that covers the surface of the recess 2Pb is also the step of the vehicle interior side wall 10 described above. It has the structure which must be coat | covered in the state which can accept the part 11. FIG. Thus, for example, as a method of solving the above-described problem, it is conceivable to provide the cover portion 2Cd of the back cover 2C in a state where the cover portion 2Cd is placed on one surface along the shape of the inner peripheral surface of the recess 2Pb. However, in such a method, in order to improve the appearance of the cover portion 2Cd, the shape of the cover portion 2Cd is adjusted by suspending or fixing the portions of the cover portion 2Cd at the corners between the constituent surfaces of the recess 2Pb. And the configuration becomes complicated. Therefore, in this embodiment, by setting a slack 2Cd4 as will be described later on the cover 2Cd of the back cover 2C, the cover 2Cd can be arranged in a simple and good-looking state, but the vehicle compartment The step portion 11 of the side wall 10 is configured to be received.

  Hereinafter, the configuration of each part of the above-described sheet 1 will be described in detail. As shown in FIG. 1, the seat back 2 includes a back frame 2F that is assembled in a square frame that forms a skeleton of each of the upper, lower, left, and right edges, and a urethane foam that is covered and provided on the front side of the back frame 2F. The back pad 2 </ b> P is made from the outside so as to cover the outer peripheral surface of the back pad 2 </ b> P, and the back cover 2 </ b> C covers the entire seat back 2 from the outer peripheral side. Here, the back pad 2P corresponds to the “seat pad” of the present invention, the back cover 2C corresponds to the “seat cover” of the present invention, and the step portion 11 of the vehicle interior side wall 10 corresponds to the “vehicle wall member of the present invention. Is equivalent to.

  In the back frame 2F, the upper part of the seat back 2 and the left and right side parts of the skeleton are continuously formed by one pipe frame 2Fa bent into an inverted U shape. A round bar-like lock pin 2Fc projecting toward the vehicle outer side is integrally coupled to the shoulder side surface of the frame portion on the vehicle outer side of the pipe frame 2Fa via the bracket 2Fb. As shown in FIG. 2, the bracket 2Fb is formed by bending a steel plate material into a U shape, and both end surfaces of the U shape are applied to the shoulder side surface of the pipe frame 2Fa on the outside of the vehicle to be strong. It is in the state welded integrally.

  The lock pin 2Fc is inserted from the outside of the vehicle into the round hole 2Fb1 formed in the surface of the bracket 2Fb facing the outside of the vehicle, and the end 2 of the lock pin 2Fb is welded to the inside of the bracket 2Fb. By being screwed together and fastened, the pipe frame 2Fa is firmly and integrally coupled. The lock pin 2Fc is a round-hole-shaped through hole formed in the cover portion 2Cd of the back cover 2C, which will be described later, after the back pad 2P and the back cover 2C are put on the back frame 2F. It is inserted into the 2Cd1a from the outside of the vehicle, and is screwed and fastened to the nut 2Fb2 of the bracket 2Fb inside thereof.

  The back pad 2P is formed in a thick mat shape that is slightly larger than the back frame 2F assembled in the above-described square frame shape, and is assembled in a state of being covered widely on the front surface portion of the above-described back frame 2F. It is designed to be set. Specifically, the back pad 2P is formed with an overhanging portion 2Pa that protrudes to the rear side of the seat at each of the upper, lower, left, and right edges, and these overhanging portions 2Pa are formed on the upper frame and the left and right sides of the back frame 2F. It is assembled in a set state so as to be wound around the frame portion from the outer peripheral side. As a result, the back pad 2P is provided in a state of covering the frame portions of the back frame 2F from the front side, the outer peripheral side, and the rear side of the seat.

  As shown in FIGS. 2 and 5, the back pad 2 </ b> P described above has the lock mechanism 12 on a part of the overhanging portion 2 </ b> Pa that covers the side surface of the shoulder opening to which the lock pin 2 Fc of the back frame 2 </ b> F outside the vehicle is attached. A recessed portion 2Pb is formed so that the stepped portion 11 of the provided compartment side wall 10 can be received. As shown in FIGS. 2 to 5, the recess 2 </ b> Pb is formed at a corner portion between the vehicle outer side surface and the rear surface of the seat back 2, and has a concave shape opening in two directions, the vehicle outer direction and the rear direction. It is formed in a concave shape having an L-shaped cross section. Specifically, the recess 2Pb has an inclined shape in which the shape of the overhanging portion 2Pa of the back pad 2P that covers the vehicle outer side surface described above becomes thinner inward toward the seat rear side. The depth of the recess in the sheet width direction is formed in a right triangular prism-shaped recess shape that becomes shallower toward the rear side of the sheet.

  More specifically, as shown in FIG. 4, the recess 2Pb has a rectangular rear surface 2Pb1 whose inner peripheral surface faces the rear side of the seat, and a rectangular surface that faces the outer side of the seat adjacent to the rear surface 2Pb1. The side surface 2Pb2 having a shape, the upper surface 2Pb3 having a right triangular shape facing the lower surface of the sheet adjacent to the rear surface 2Pb1 and the side surface 2Pb2, and the rear surface 2Pb1 and the side surface 2Pb2 so as to face the upper surface 2Pb3. The lower surface 2Pb4 having a right triangular shape with the surface facing the upper side of the sheet is formed in a right triangular prism-shaped concave shape. Strictly speaking, the back surface 2Pb1, the upper surface 2Pb3, and the lower surface 2Pb4 of the concave portion 2Pb are formed so that the surfaces are inclined obliquely toward the outside of the vehicle, and the step of the concave portion 2Pb is made gentle. . The side surface 2Pb2 of the recess 2Pb described above has a shape from the base with the back surface 2Pb1 to the front of the region through which the lock pin 2Fc is passed, but there is no shape on the rear side from the base 2Pb5.

  As shown in FIGS. 2 and 5, the lock pin 2Fc is passed through the space 2Pb5 vacant on the rear side of the side surface 2Pb2 of the recess 2Pb to the inside, and the bracket 2Fb coupled to the back frame 2F described above. And are fixed by screwing. Thereby, the lock pin 2Fc is provided so as to pass through the concave shape of the concave portion 2Pb, and even if the substantial protrusion length exposed on the seat rear side is long, the seat back 2 The overhanging length beyond the width is kept short.

  As shown in FIG. 5, the back cover 2 </ b> C includes a fabric front side covering portion 2 </ b> Ca covering the front side region of the seat back 2 and a carpet back side covering portion 2 </ b> Cb covering the rear side region of the seat back 2. It is configured to be stitched into a bag. The front side covering portion 2Ca is thinner than the back side covering portion 2Cb made of the carpet material described above, and is formed of a fabric material rich in stretchability and flexibility. The front side covering portion 2Ca is placed so as to cover the front and top surfaces of the seat back 2 and the left and right side surfaces. Further, the back side covering portion 2Cb is formed of a carpet material that is thicker than the front side covering portion 2Ca made of the above-described fabric material and has low stretchability and high rigidity. This back side covering portion 2Cb is covered with the rear surface of the seat back 2 covered.

  The front side covering portion 2Ca and the back side covering portion 2Cb described above are stitched so that the edges from the upper edge portion to both shoulder openings are joined together to form a single sheet, so that the seat back 2 can be seen from above. It is set as the state formed in the bag-like shape opened on the lower side which can be attached and set. Further, the front side covering portion 2Ca and the back side covering portion 2Cb have a configuration in which a line fastener 2Cc capable of coupling or removing them is provided between the left and right side edge portions. When these linear fasteners 2Cc are located at the upper ends of the respective line fasteners 2Cc when the slider for coupling the respective engagement teeth is positioned, the respective edges and the back side of the front side covering portion 2Ca are regarded as being disconnected. Each edge portion of the covering portion 2Cb is in a state of being opened to each other, and each slider is lowered to connect each tooth, so that each edge portion and the back side covering portion of the front side covering portion 2Ca Each edge of 2Cb is connected to each other to be in a closed state.

  Therefore, the above-described back cover 2C is set in such a manner that the line fasteners 2Cc are opened in advance, the back cover 2C is set on the seat back 2 from the upper side, and then each line fastener 2Cc is closed to cover the front side. By setting each edge portion of the portion 2Ca and each edge portion of the back side covering portion 2Cb to be coupled to each other, the two pads 2P are set so as to be in close contact with the entire surface of the back pad 2P. .

  Here, the front side covering portion 2Ca described above is covered in a state where the whole is widely adhered along the shape of the back pad 2P with the bulging back surface (the shape having the side supports 2Ps on both the left and right sides). In addition, a plurality of face materials formed in accordance with the shape of each undulating surface of the back pad 2P are sewn together and joined together. And the surface side covering portion 2Ca is suspended in a boundary groove 2Pc formed along the boundary line of the portion where the seam seam 2Ca1 between the joined face materials is undulated in the valley shape of the back pad 2P. Rarely, it is fixed, or it is in a state of being inserted into a boundary groove 2Pd formed along a boundary line of a portion of the back pad 2P that swells in a mountain shape. Thus, the front side covering portion 2Ca is bent and stretched in a state of being in close contact with the surface of the back pad 2P so as not to float from the surface of the back pad 2P or cause wrinkles.

  Further, the back side covering portion 2Cb is stretched in a state of being bridged between the overhang portions 2Pa projecting to the rear side of each frame portion of the back frame 2F of the back pad 2P. As a result, the back side covering portion 2Cb maintains the shape of the rear surface of the seat back 2 with a good touch feeling and receiving an external load by a structure having moderately hard rigidity formed by the thick carpet material. It is in a state where it is covered in a state where it can be used.

  As shown in FIG. 4, the back cover 2 </ b> C described above is formed with a cover 2 </ b> Cd having a slack 2 </ b> Cd <b> 4 that is spherically recessed in the recess 2 </ b> Pb in the region covering the recess 2 </ b> Pb of the back pad 2 </ b> P. . The covering portion 2Cd extends rearward from the first piece 2Cd1 formed of the same thick carpet material as the back side covering portion 2Cb described above and the rear edge facing the recess 2Pb of the front side covering portion 2Ca. And the second piece 2Cd2 formed.

  The first piece 2Cd1 is generally formed in a rectangular shape that is long in the seat height direction, and is disposed so as to cover most of the recess 2Pb from the outside. The first piece 2Cd1 has a rear edge thereof connected to the outer edge of the vehicle on the back side covering portion 2Cb described above by integrally stitching the upper region thereof, The remaining lower region is connected to a state where it can be connected or disconnected by the above-described line fastener 2Cc. The above-described line fastener 2Cc extends to a position higher than the position where the lock pin 2Fc is disposed, and the first piece 2Cd1 described above can be opened from the back side covering portion 2Cb to a position higher than the lock pin 2Fc. It is like that. Thus, when the back cover 2C described above is put on the back pad 2P from above, the through hole 2Cd1a formed in the central portion of the first piece 2Cd1 for allowing the lock pin 2Fc to pass therethrough is the back frame 2F described above. The operation of aligning with the round hole 2Fb1 of the bracket 2Fb coupled to the first part 2Cd from the position where the line fastener 2Cc is opened can be easily performed by directly touching the part near the through hole 2Cd1a of the first piece 2Cd1. ing.

  The above-described first piece 2Cd1 is disposed across the above-described recess 2Pb in the height direction, and the upper edge portion and the lower edge portion thereof are respectively on the front side at positions where the recess portion 2Pb exceeds the recess direction 2Pb. It is made into the state stitched | sutured with the adjacent edge part of coating | coated part 2Ca. The first piece 2 </ b> Cd <b> 1 is formed such that a front edge thereof projects in an arc shape on the front side of the seat. Specifically, the protruding shape of the first piece 2Cd1 to the front side of the seat has the maximum protruding length at the height position where the lock pin 2Fc is disposed, and from there both sides in the seat height direction. An arcuate projecting shape in which the projecting length toward the front side decreases toward the front is formed.

  When the first piece 2Cd1 is pressed against the side surface 2Pb2 of the recess 2Pb, the length in the front-rear direction of the first piece 2Cd1 projects most greatly to the front side of the seat at the front edge described above. The length is set at a position where the portion is substantially aligned with the front edge of the side surface 2Pb2 of the recess 2Pb (a position slightly shorter than that). Thus, as shown in FIG. 2, the first piece 2Cd1 described above is hung over the back surface 2Pb1 of the recess 2Pb when a force is applied to the side surface 2Pb2 of the recess 2Pb as described above. Thus, the bending is prevented from being hindered by the hardness, and it is configured to be pressed into a state of being in close contact with the side surface 2Pb2 of the recess 2Pb with a light force.

  In addition, the first piece 2Cd1 described above is in a state of being disposed across the recess 2Pb in the height direction as described above, but the first piece 2Cd1 connected to the front edge thereof as described later. Along with the two pieces 2Cd2, it floats from the inner peripheral surface of the recess 2Pb and is provided with a slack 2Cd4 that is spherically recessed in the recess 2Pb. Thereby, even if the force pressed against the side surface 2Pb2 of the recess 2Pb as described above is applied to the first piece 2Cd1 described above, the slack 2Cd4 is stretched so that a large tension is not applied. It is configured to be pressed against the side surface 2Pb2 so that an unreasonable load is not applied to each step on the upper and lower sides of the recess 2Pb. Further, the first piece 2Cd1 has a rigidity that is exhibited by being bridged across the concave portion 2Pb by being in a state of being arranged across the concave portion 2Pb in the height direction, From the state where the upper and lower edges are bent to the position where the above-mentioned slack 2Cd4 is stretched by the tensile force exhibited by stitching the upper side covering portion 2Ca to the front side covering portion 2Ca, further bending toward the inner side of the seat It is configured to be difficult. As a result, the first piece 2Cd1 does not sink significantly into the empty 2Pb5 formed at the rear part of the side surface 2Pb2 of the recess 2Pb.

  On the other hand, since the second piece 2Cd2 is a part formed extending from the front side covering portion 2Ca to the rear side, the second piece 2Cd2 is softer than the first piece 2Cd1 made of the carpet material, and The structure is rich in extensibility. The second piece 2Cd2 described above is formed in a shape in which a rear edge portion joined to the first piece 2Cd1 projects in an arc shape on the rear side of the seat. The shape of the second piece 2Cd2 projecting to the rear side of the seat is the same as the shape of the edge of the front side of the first piece 2Cd1 described above at the height position where the lock pin 2Fc is disposed. In this way, an arcuate projecting shape is formed in which the projecting length toward the rear side becomes smaller in both directions in the seat height direction.

  The second piece 2Cd2 has a rear edge projecting in an arc shape on the rear side thereof and a front edge projecting in an arc shape on the front side of the seat of the first piece 2Cd1. . Thus, the second piece 2Cd2 is sewed into a bag shape having a slack 2Cd4 that is recessed spherically into the recess 2Pb together with the first piece 2Cd1. Specifically, the second piece 2Cd2 and the first piece 2Cd1 are in a state of being folded back and stitched so that the seam allowance 2Cd3 is located on the back side facing the recess 2Pb. Accordingly, the first piece 2Cd1 and the second piece 2Cd2 sewn in the bag shape are always held in a recessed shape in the recess 2Pb by the rigidity of the seam allowance 2Cd3 sewn in the arc shape. The holding force is applied. Accordingly, the cover portion 2Cd formed by stitching the first piece 2Cd1 and the second piece 2Cd2 is held in a state of having a slack 2Cd4 that is spherically recessed in the recess 2Pb in the free state. ing. Thus, even if the cover portion 2Cd has a shape having the slackness 2Cd4, the surface of the cover portion 2Cd is always in a state in which the slackness 2Cd4 is urged into a spherically recessed shape in the recess 2Pb. It is designed to be kept in a good-looking state with tension and no wrinkles.

  As shown in FIG. 5, the cover portion 2Cd has a depth of the slack 2Cd4 that is spherically recessed in the recess 2Pb, which is shallower than the depth of the recess 2Pb, and the step portion of the compartment side wall 10 in the recess 2Pb. At all times before 11 is pushed in, it is in a state of being kept floating from the recess 2Pb. As shown in FIG. 2, the cover portion 2Cd has a slack 2Cd4 stretched by the stepped portion 11 being pushed by the stepped portion 11 of the vehicle compartment side wall 10 being pushed into the recessed portion 2Pb. Then, the recess 2Pb is deformed so as to be pressed against the side surface 2Pb2 and the back surface 2Pb1. Specifically, the cover 2Cd is deformed so that the first piece 2Cd1 is pressed against the side surface 2Pb2 of the recess 2Pb with little extension because the first piece 2Cd1 is more rigid and difficult to expand than the second piece 2Cd2. Then, the second piece 2Cd2 is deformed so as to be pressed against the back surface 2Pb1 of the recess 2Pb while slightly expanding its shape so as to absorb the difference in circumference.

  The extension amount of the second piece 2Cd2 is small because the slack 2Cd4 is set in the cover portion 2Cd. Thereby, the cover portion 2Cd is formed along the shape of the recess 2Pb so that the seam allowance 2Cd3 of the first piece 2Cd1 and the second piece 2Cd2 is pushed into the corner portion of the side surface 2Pb2 and the back surface 2Pb1 of the recess 2Pb. It fits and deforms well. As described above, when the stepped portion 11 of the passenger compartment side wall 10 is pushed into the recess 2Pb, the slack 2Cd4 of the cover portion 2Cd that is recessed in a spherical shape is stretched along the shape of the inner peripheral surface of the recess 2Pb. Therefore, the step portion 11 of the passenger compartment side wall 10 can be simply pushed into the recess 2Pb.

  Further, even in the cover portion 2Cd, the first piece 2Cd1 is forcibly pulled because the stepped portion 11 of the passenger compartment side wall 10 is not forced to be pulled by the force pushed into the recess 2Pb. Thus, there is no possibility that the through hole 2Cd1a through which the lock pin 2Fc is passed is strongly hooked to the lock pin 2Fc. Strictly speaking, the first piece 2Cd1 is displaced in a direction in which the through hole 2Cd1a is slightly misaligned with respect to the lock pin 2Fc by the bending deformation pressed against the side surface 2Pb2 of the recess 2Pb, but the through hole 2Cd1a However, since the first piece 2Cd1 is made of a thick carpet material and is not easily torn, the first piece 2Cd1 is not easily broken. The periphery of the through hole 2Cd1a of the one piece 2Cd1 is not torn.

  Accordingly, the lock pin 2Fc projecting into the recessed space of the recess 2Pb is stepped from the receiving port 11A formed in the step 11 as the step 11 of the vehicle compartment side wall 10 is pushed into the recess 2Pb. It enters the portion 11 and is locked by being pushed into the lock mechanism 12 provided in the inside. Note that the configuration of the lock mechanism 12 is the same as a known configuration disclosed in a document such as Japanese Patent Application Laid-Open No. 2008-184099, and a specific description thereof will be omitted.

  Thus, the seat 1 according to the present embodiment includes a back pad 2P (seat pad) having a recess 2Pb into which the step portion 11 (other member) of the passenger compartment side wall 10 is pushed, and the back pad. And a back cover 2C (seat cover) covered on the surface of 2P. The cover portion 2Cd is configured to have a slack 2Cd4 that is longer than the linear distance between the opening edges of the recess 2Pb and is covered in a state of floating from the inner peripheral surface of the recess 2Pb. When the step portion 11 of the compartment side wall 10 is pushed into the recess 2Pb, the cover portion 2Cd is pressed against the inner peripheral surface of the recess 2Pb so that the slack 2Cd4 is stretched and the step portion 11 of the compartment side wall 10 is stretched. The push is accepted.

  Since the slack 2Cd4 is set in the cover 2Cd of the back cover 2C as described above, the cover 2Cd is lifted from the recess 2Pb at all times before the step 11 of the vehicle compartment side wall 10 is pushed into the recess 2Pb. In this position, the recess 2Pb is covered with a gentle surface shape having the slack 2Cd4. Therefore, with the simple configuration in which the slack 2Cd4 is set in the cover portion 2Cd, the formation portion of the recess 2Pb can be normally covered with the cover portion 2Cd in a good appearance. The cover portion 2Cd has the step portion 11 of the vehicle compartment side wall 10 stretched by the slack 2Cd4 in such a manner that the step portion 11 of the vehicle compartment side wall 10 is pushed into the recess portion 2Pb and pressed against the inner peripheral surface of the recess portion 2Pb. Accept the push. As described above, the back cover is configured so as not to cause a problem even when the stepped portion 11 of the compartment side wall 10 is pushed into the back pad 2P having a concave shape by the simple configuration in which the slack 2Cd4 is set in the cover portion 2Cd. 2C can be easily stretched.

  Further, the cover 2Cd is provided in a state of being slacked into a curved shape so as to be spherically recessed in the recess 2Pb. Thus, by providing the cover portion 2Cd so as to be curved so as to be recessed in a spherical shape, the cover portion 2Cd can be coated with a good appearance so as to cover the formation portion of the recess 2Pb with a gentle concave shape.

  Further, the cover portion 2Cd is configured by connecting a plurality of pieces of flexible surface-like pieces, and the seam allowance 2Cd3 between these pieces is set on the back surface side facing the recess 2Pb. Thus, by setting the seam allowance 2Cd3 between the pieces of the cover part 2Cd on the back side facing the recess 2Pb, the seam allowance 2Cd3 makes it easier for the cover part 2Cd to receive an urging force in the direction of entering the recess 2Pb. . Therefore, with such a simple configuration, the cover portion 2Cd can be normally held in a state in which the cover portion 2Cd is disposed in a good-looking state loosened in the recess 2Pb.

  Moreover, the recessed part 2Pb is formed in the recessed shape opened in two directions by cross-sectional L-shape. The cover 2Cd is configured by connecting a first piece 2Cd1 that covers the side surface 2Pb2 (one surface of the L shape) of the recess 2Pb and a second piece 2Cd2 that covers the back surface 2Pb1 of the recess 2Pb. . The first piece 2Cd1 has a surface shape that matches the side surface 2Pb2 of the recess 2Pb and is configured to be more rigid than the second piece 2Cd2. The second piece 2Cd2 has a shape with a shorter cross-sectional length than the back surface 2Pb1 of the recess 2Pb, and is configured to be more extensible than one piece.

  As described above, since the rigidity of one piece (first piece 2Cd1) is high, the urging force inward in the recess 2Pb by the seam allowance 2Cd3 set on the back side of both pieces is easily increased, and the covering portion 2Cd However, it is easy to be held in a state of slack in the recess 2Pb. Further, since the other piece (second piece 2Cd2) is highly extensible, when the step portion 11 of the vehicle compartment side wall 10 is pushed into the recess 2Pb, the highly rigid first piece 2Cd1 is inserted into the recess 2Pb. The second piece 2Cd2 having high extensibility is applied across the side surface 2Pb2 and the back surface 2Pb1 of the recess 2Pb, or is applied to the back surface 2Pb1 of the recess 2Pb while being applied to the side surface 2Pb2. Can be easily bent. Therefore, the cover 2Cd can be easily bent along the shape of the recess 2Pb.

  Further, a lock pin 2Fc protruding through the first piece 2Cd1 is provided on the side surface 2Pb2 of the recess 2Pb. With this configuration, when the lock pin 2Fc is pushed into the lock mechanism 12 provided on the step portion 11 of the compartment side wall 10 to be locked, the step portion 11 is pushed into the recess 2Pb. Since the cover portion 2Cd of the back cover 2C has the slack 2Cd4, a large tension is not applied, and no excessive load is applied between the lock pin 2Fc and the first piece 2Cd1 passing therethrough. Therefore, the lock pin 2Fc can be smoothly locked to the lock mechanism 12 provided in the step portion 11 of the vehicle interior side wall 10 without applying an excessive load to the cover portion 2Cd of the back cover 2C.

  As mentioned above, although the embodiment of the present invention has been described using one example, the present invention can be implemented in various forms in addition to the above example. For example, in the “vehicle seat” of the present invention, the wide side seat divided into 6: 4 on the left and right of the rear seat of the automobile, the seat equally divided on the left and right, and the left and right seats are integrated. It can also be applied to a seat for three people, a seat in the center seat where the seats are provided adjacent to both the left and right sides, a seat applied to vehicles other than automobiles such as railways, The present invention can be widely applied to seats used for various vehicles such as aircraft and ships. The configuration of the present invention can be applied not only to the seat back of a vehicle seat but also to a seat cushion.

  Moreover, the recessed part formed in a seat pad is not restricted to what is dented in the square shape, What was dented in the curved shape, and what was formed as a hollow shape penetrated may be sufficient. Further, the recess may be formed in an intermediate portion of the seat pad and open only in one direction. Further, the other member that may be pushed into the concave portion is not limited to the vehicle wall member, but may be a component member of the seat or some member installed in the vehicle.

  Further, the seat cover covered on the surface of the seat pad may be made of leather in addition to fabric material and carpet material. Moreover, the cover part which coat | covers the recessed part of a seat cover may be formed by connecting the face material of the same material. In addition, the entire cover portion of the seat cover does not need to be disposed so as to float from the inner peripheral surface of the recess, and a part thereof may be provided in contact with the inner peripheral surface of the recess. Further, the slack formed in the cover part may be swelled and slackened in the direction opposite to the direction entering the concave part. Further, the slackness of the cover part is not limited to a shape that is curved in a spherical shape, but may be a shape in which the flat surface is curved and slackened, or a shape that is bent in a sawtooth shape and slackened.
